Is Your Home WiFi Good Enough?

Is your Home WiFi good enough?

Wi-Fi has forever changed the way we live, work and play. We can surf the internet in the home or on holiday by the pool, look up a recipe in an instant, and even connect our lights to voice control. It’s no wonder it was accepted with open arms, but is your Wi-Fi as good as it needs to be?

10 years after Wi-Fi first made its way into homes, it’s evolved into a juggernaut of speed and accessibility that we can’t do without, but think about how many wireless devices your home has – the average home has at least 10 devices connected wirelessly to the internet, many have more.

While older devices are typically happy with a slice of slow internet, your newer devices like 4kTVs and media streaming simply can’t function without fast internet. Add in a game console, tablet, a few smartphones and a laptop or two, and your Wi-Fi is suddenly stretched beyond full capacity and struggling to keep up.

Yet, most people don’t know how fast their Wi-Fi is, or if it’s working right– they only know how many bars they’ve got. Unfortunately, counting bars can be misleading.

Here’s why relying on your Wi-Fi bar count might be ruining your internet experience:-

Bars measure the wrong thing

While it’s great to know you’ve got a ‘strong’ signal, it would be even better if you could have a ‘fast and available’ internet signal. The fact is that the internet could actually be down and you’d still have full bars because it’s really only measuring how close to the Wi-Fi router you are.

That proximity measure doesn’t take into account how many devices are fighting for the same bandwidth or whether there’s any left for you.

Wi-Fi goes sideways

While next-door’s Wi-Fi can reach the back of their property, it can also go a similar distance sideways into your house. This extra ‘noise’ can disrupt and slow down your own Wi-Fi. In dense areas, your Wi-Fi is basically getting lost in a swirling field of signals, all using the same channel and frequency. It’s a digital crowd which can seriously slow your speeds.

This can be fixed by changing your Wi-Fi channel to one with less cross-talk.

Everyone uses the default settings

Most home Wi-Fi uses a 2.4ghz frequency by default. Whilst it makes a ‘Plug & Play’ router easy to set up, it does mean you’re not getting the speeds you could be. Switching to the 5ghz frequency means your Wi-Fi is separated from the neighborhood cross-talk. 5ghz is also considerably faster, which is a bonus.

Priority isn’t set

While not Wi-Fi specific, there is also a “Quality of Service” setting if your router supports it. This allows things like Netflix and Skype calls to always take priority and remain uninterrupted over less important tasks like downloads.

You’ll be able to watch movies with less of those awful buffering jumps and video chat without freezing.

What to do if your Hard Drive Fails

Hard drives fail eventually

If your hard drive is going bad, chances are strange things are happening and you’re a little panicked.

It’s where you put your digital memories, your household files and maybe work that you’ve been doing for months. As far as you’re concerned, that hard drive IS the computer and failure is not an option.

Perhaps it was overheated, knocked around or came from the factory with a flaw. Unfortunately, all hard drives will fail eventually. So how do you know if it’s definitely the drive and what should you do?

Start by watching for these signs: –

Computer slowing down

Because standard hard drives contain moving parts, the slower it gets, the slower your computer gets. It’s a bit like a record player, with spinning plates and a needle whipping from side to side, except the needle doesn’t actually touch the disc.

Your hard drive may eventually take longer to spin up and longer to retrieve files, which will have an impact on everything from booting up to playing games.

Blue screen of death

A classic Windows error, this is when your computer locks up to only show a blue screen with an error code, which while it does mean something specific has gone wrong, can always be translated loosely to ‘nope, not today’.

The more often your computer does this, the more severe the problem is and although it can be caused by other things as well as the hard drive, if blue screen happens it is a critical issue.

Not booting up

During the initial bootup stage, your computer is loading a program stored on the hard drive – it’s your operating system e.g. Windows or MacOS. If some of the files have a problem (because the hard drive has a problem) or they can’t be found, the computer won’t boot. Errors vary, but the outcome is the same.

Corrupted files

Sometimes a file won’t open because the computer says it is corrupted. Some essential pieces of the file are missing, and unlike a book where a missing page is only inconvenient, it’s a deal breaker for computer files.

Noises

You’re familiar with the normal noises your computer makes, but as the hard drive fails the noises can change. You might hear clicking, grinding or even a sci-fi phaser noise. Noises will get louder or speed up during heavy file access.

Whenever something is clearly wrong, the key is to stop and turn your computer off. Continued use can result in more data loss.

Even if you don’t have a backup yet, turn it off now because the large task of backing up can cause extra strain on an already delicate hard drive. It’s tempting to hurry and try to get a quick copy of your files, but in these cases, it’s not about time – it’s about the extra spinning, scratching, warping and electrical charge, all dissolving your precious data with each access.

If you have problems with your hard drive, give us a call on 01455 209505 – we’re happy to help.

Search Google More Safely

Search Google more safely

We all use Google, quickly finding everything we need on the Internet. It’s replaced dictionaries, encyclopedias, instruction manuals, newspapers and in many cases, even doctors (not such a good thing!).

However, sometimes your search results aren’t the real thing and can be downright malicious. For example, we regularly find that customers search for, say, a printer driver software update and they type in something like “XP442 printer driver” . A close look at some of the results shows things like ‘ epsondrivers.org ‘ or ‘ printerdriversforyou.com ‘ – not the manufacturers official website – so you may get a driver but you are very likely to get something unwanted too!

Here’s how to search more safely: –

Pay attention to the URL in Google

Below every result title there’s a URL (website address) in green. No matter what the title says, this URL is where your mouse click will take you. Unfortunately, cyber-criminals will often list their site with a familiar and trusted title but link you to their scam/malware pages.

Another example can be the title of your bank name (eg, Example Bank), which seems legitimate, but the URL could be www.baabpjhg.com which is obviously not your bank. Sometimes they’ll attempt to trick you by putting the real site into the link too, eg www.baabpjhg.com/examplebank.com which makes it even more likely to catch you out when skimming through results quickly. When you visit the page, it might look exactly like your bank’s site and ask for your login details, which are then harvested for attack.

Whilst jibberish in the link is pretty easy to spot, sometimes they’ll take advantage of a small typo that you can easily miss. For example, www.exampebank.com (missing the letter L).

Notice Google search results v paid adverts

Google does a pretty good job at making sure the most relevant and legitimate sites are at the top of the list, however paid adverts will usually appear above them. Much of the time, these paid ads are also legitimate (and you can quickly check the URL to verify), but occasionally cybercriminals are able to promote their malicious site to the top and catch thousands of victims before being removed.

Similarly, well known businesses can pay for adverts, even though much of their software is classed as ‘Potentially Unwanted Programs’ and technicians remove them from computers every day.

Believe Google’s malicious site alerts

Sometimes Google knows when something is wrong with a website. It could be a legitimate site that was recently hacked, a security setting that’s malfunctioned, or the site was reported to them as compromised.

When this happens, Google stops you clicking through with a message saying “this website may be harmful” or “this site may harm your computer”. Stop immediately, and trust that Google has detected something you don’t want in your house.

Turn on Safe Search

You can filter out explicit search results by turning on Google Safe Search. Whilst not strictly a cyber-security issue, it can still provide a safer Google experience. Safe Search is normally suggested as a way to protect browsing children, but it also helps adults who aren’t interested in having their search results cluttered with inappropriate links, many of which lead to high-risk sites.

Switch Safe Search on/off by clicking Settings > Search Settings > Safe Search.

These are just a few tips to make your searching safer, but the most important is you – never take your internet security for granted and always be cautious when using any search engine, as they can only display what they find out there on the internet – good and bad.

How to tell if your Computer has a Virus

How to tell if your computer has a virus

Sometimes computers do strange things that ring alarm bells and the next thing is that you’re running virus scans and demanding everyone come clean about their browsing habits. Fortunately, not all weird occurrences are caused by viruses – sometimes your computer is simply overloaded, overheating or in desperate need of a reboot.

Here are some tell-tale signs of a malware attack:-

1. Bizarre error messages

Look for messages popping up from nowhere that make no sense, are poorly worded or plain gibberish – especially if they’re about a program you don’t even have. Take note of anti-virus warnings too, check the warning is from YOUR anti-virus software and also that it looks like it should.

If a message pops up that isn’t quite right, don’t click. Not even to clear or cancel the message. Close the browser or shut down the computer instead, then run a full scan.

2. Suddenly deactivated anti-virus/malware protection

Certain viruses are programmed to take out the antivirus/antimalware security systems first, leaving you open to infection (this is why we advise our customers to always have all the system tray icons visible on the taskbar, on the bottom right-hand side). If you reboot and your protections aren’t back doing their job, you may be under attack. Attempt to start the anti-virus manually.

3. Social media messages you didn’t send

Are your friends replying to messages you never wrote? Your login details might have been hacked and your friends are now being tricked into giving up personal information or worse. Change your password immediately, and advise your friends of the hack.

4. Web browser acting up

Perhaps you’ve noticed your homepage has changed, it’s using an odd search engine or opening/redirecting to unwanted sites. If your browser has gone rogue, it could be a virus or malware, usually one intended to steal your personal or financial details.

Skip the online banking and email until your scans come up clear and everything is working normally again.

5. Sluggish performance

If your computer speed has dropped, boot up takes longer and even moving the mouse has become a chore, it’s a sign that something is wrong – but not necessarily a virus. Run your anti-virus scan and if that resolves it, great. If not, your computer possibly needs a tune-up or quickie repair.

6. Constant computer activity

You’re off the computer but the hard drive is going, the fans are whirring, and the network lights are constantly flashing? Viruses and malware use your computer resources, sometimes even more than you do. Take note now of what’s normal, and what’s not.

Too Many Passwords? Try a Password Manager

Keep your computer secure from scammers

One of the regular things we see is customers struggling with the number of passwords they need to remember – so many login details are needed these days. As we have advised previously, it is not a good idea to have just one password for everything so how can you keep track of all of them?

You can try using a Password Manager – this is a program or browser extension that allows you to store passwords in an encrypted form on your device, but also do much more. The bonus is that all you need is one Master password to manage it.

The passwords are saved in an encrypted password ‘vault’ and when you go to a specific website, the Password Manager inputs the password for you. Whilst many browsers already do this for you, a Password Manager does it in a more secure way.

Some Password Managers advise you as to how secure your passwords are – preferably using a mixture of letters, numbers, capitals and special characters. Some can automatically change passwords for you and as well as set up two-factor authentication – this is where you can open the password vault with your Master password, but you also use some form of verification (such as getting a code texted to your phone), which you type in to prove that you are authorised to access those important password details.

The main point is that you would not need to remember large numbers of passwords, which means that you can easily keep your online accounts as secure as possible.

There are a many Password Managers – here is a selection of the best known ones: –

LastPass

This is one of the original Password Managers and installs a browser extension or mobile app. With one master password you can access the password vault and manage passwords for all websites that you log into. It can even generate secure passwords for you.

At the moment the browser extension is free to use and more services are available in the premium version.

True Key

Intel has produced a Password Manager that is free to use for 15 passwords, which is enough for many people, and also a premium version which allows more and extra services. As well as the usual encrypted password facility, it allows multiple ways to access the password vault – master password, second device, email or even facial recognition.

Dashlane

As well as storing your passwords securely, this product helps you by providing a rating of your password security strength. The premium version also allows synching across multiple devices as well as two-factor authentication.

These are just three of the many Password Managers out there but whatever one you choose, do make sure that it is from a reputable company. If using a search engine, take particular care checking the website address the download is coming from as it needs to come from the company itself and not an address that is only similar.

Also you need to remember that whilst Password Managers help you keep track of your password security, you still need to maintain effective security software and keep a cautious eye on what you download from the internet.

NHS Cyber Attack – how to build up your protection

Malware terms

Here is some more information about the NHS cyber-attack that started on Friday.

The Ransomware variant is called WanCrypt0r and 81,000 infections were reported in the first 12 hours. It has not only targeted the NHS but has also gone for Banks, Telecoms and Utilities worldwide.

It has been established that the criminals are exploiting a known vulnerability in Windows (MS17-010)  which has already been patched, but those computers which do not have up to date Windows Updates are still vulnerable.

We have warned customers before about the Ransomware threat and the extent of this attack means that we should all consider increasing our defences, especially businesses but also homes, as Ransomware can be spread via emails.

As there is no way to guarantee 100% protection against threats, we have to make it as difficult as possible for the threat to take hold and how much you decide to do depends on the level of risk you wish to take.

1. Ensure that Windows Updates is kept up to date

Windows Updates contain security fixes (amongst other things) and computers that have not been kept up to date are vulnerable, as in the case in this attack. Admittedly Windows 10 gives you little choice when it comes to Updates (you have to have them) but if you are using any previous version of Windows – make sure that Updates are kept up to date.

If you are still using Windows XP or Vista, you shouldn’t be. These versions of Windows no longer get Windows Updates.

Update:
Microsoft have now issued a patch for XP and Vista. Go to this web page to download the patch if you are still using XP and Vista (demand is high so it may take more than one try). Please note – this patches this vulnerability only so you should still move away from these unsupported operating systems.

2. Make sure that you have a good antivirus product that is kept up to date

Good security products give a better degree of protection but they have to be kept up to date, with active subscriptions. Free antivirus is better than nothing but does not give protection that is as comprehensive as paid versions.

3.    Install extra protection.

Usually, you should not have more than one security product installed on your computer at any one time, but there is a product called Malwarebytes, which can be installed as well as your existing antivirus. This increases your protection especially from Ransomware, if you install the premium version.

4.    Consider your backup situation

If a computer is infected, the virus goes across a network and it is possible that any connected storage will also get infected – this includes cloud storage such as Dropbox. Having said that, Dropbox state that within 30 days of the event they can restore your files (here) and you can subscribe to extend the 30 days to 1 year if you choose. If you are using any other Cloud storage, check with them to see if they have a similar service.

It is vital that your important files are backed up and a copy kept separate from your computer. In the event of an infection, you can at least relax a little that your important data has not been encrypted.

5.    Consider downtime – system backups

When a computer has Ransomware, if you have backups of important files you will not need to pay the criminals. It is likely that the computer will need to be wiped clean and Windows reinstalled, which takes time.

There is software available that can take a copy of your whole computer, which could be used to reinstall the whole system in much less time than a full reinstall. A copy once every 2 or 3 months would allow you to get back up and running in much less time.

As mentioned earlier, many viruses are spread through emails, so never click on links in emails and do not open attachments unless you know that they are genuine emails – if in doubt call the sender.

If you would like help with any of the above, give us a call on 01455 209505.

Mac Computers and Viruses – Truth versus Myth

Compromised app containing a virus

We have lost count of the number of times that we’ve heard the phrase “Macs don’t get viruses” or “I’ve never had protection on my Mac”. Whilst this may have been true in the past it isn’t as cut and dried today and the Mac OSX operating system actually can be vulnerable, so protection is worth seriously considering especially in a work or business situation.

More difficult to exploit

The Mac is based on the UNIX operating system (as is Linux) which is more difficult to exploit as it is built on a sandbox-type principle, where malicious code cannot usually get as far as it might get in a non-UNIX based system.  Also, Apple has built in a certain degree of malware prevention in the Mac, for example their ‘Gatekeeper’ software actually blocks apps that have been downloaded from the internet (i.e. anywhere other than the Apple Store) that do not have a Developer ID supplied by Apple certifying that they are safe to use.

Unfortunately, in spite of this robustness the Mac is now becoming a victim of its own success because its increasing popularity means that cybercriminals are paying more attention to it – and finding ways of making money from you even if you are a Mac user. It’s not just that popularity – Macs are usually much more expensive to buy, so the cybercriminals may believe that Mac users are attractive targets.

Not impossible to exploit

For example, a popular Mac DVD-ripping and Video Conversion app called ‘Handbrake’ was recently compromised, by criminals hacking the software company download server and inserting malicious code into the app download. When this download was installed on a Mac, it also installed a ‘backdoor’ (a means of bypassing security). The user then was asked for their administrator password, which was passed over the internet in plain text so that the criminals could access any part of the system from that point.

By successfully avoiding having to use the ‘direct attack’ approach, this allowed important information such as password keychains and browser data to be extracted and passed to the crooks.

This compromise has now been corrected and the infected code was from a download between 2nd and 6th May 2017. If you have installed Handbrake version 1.0.7, check the SHA1 checksum of the file by opening a Terminal, typing in shasum and dragging the installation file into the Terminal Window.

If the checksum is 0935a43ca90c6c419a49e4f8f1d75e68cd70b274 then the file is malicious.

To disinfect it remove the Launch Agent plist file fr.handbrake.activity_agent.plist, and the activity_agent.app file located in ~/Library/RenderFiles/. Reboot then change your passwords.

In the past year or so a Ransomware-type malware was discovered for the Mac, so this isn’t the first time that there has been a potential issue.

Even though the Mac is more robust and secure than its main competitor, it is by no means invulnerable to malicious code and it is a risk to think otherwise. You may feel that the risk is small enough to continue to use your Mac as you always have, but at least consider the pros and cons first – as well as being very careful about where you get your apps from.

Helping to Control Spam in your Email

Getting rid of Spam in your Inbox

‘Spam’ emails get into everyone’s email Inbox and are a fact of life these days. Whether its “Russian Brides” or something else, Spam emails are annoying, especially if you regularly get a large number every day. It is not surprising that there is so much, as current estimates put Spam between 60%-80% of global email, depending on which report you read.

What many people do not realise, is that a lot of Spam emails are caught by your email company and discarded before you even get to see them – although some email companies filter out Spam much better than others do.

Having said that, there are ways to help reduce the number of Spam emails that you get – here are a few of them: –

Mark as Spam before doing anything

This is the most important thing. More often than not, we see that customers tend to delete the Spam emails, then carry on reading their ‘proper’ emails as normal – all this does is just delete it, so it doesn’t help you the next time they send an email from that address.

What you need to do is to mark the email as Spam, before deleting it. This tells your email company or email program what to do if this email address sends another email – that is get rid of it before you get it.

Email using Webmail

If you are using Webmail (getting your email through the email company website), mark the Spam email (usually on the left-hand side) and click on the Spam button, which may be marked as ‘Report’, ‘Spam’ or something similar. This identifies the email as Spam and tells the email company that you don’t want any more emails from that email address. The email company should automatically send any more emails from the same address, straight into the ‘Junk’ folder instead of your Inbox.

Email using an Email Program or App

Many email programs include a facility to mark an email as Spam. For example, if using Outlook, right-click the email(s) and select ‘Junk’. You will get options as to what to do, e.g. selecting ‘Block Sender’ (blocking just the email address) or ‘Block Senders Domain’ which will block all emails from the name after the ‘@’ symbol. Note that Outlook diverts emails into the Junk folder – they will still be coming from the email company.

Most email programs will have a similar method of diverting spam that has been received.

Many (non-free) security software programs include an anti-Spam facility, whether it blocks an email that it knows is spam using its own built-in spam filters, or “training” the program by marking the Spam emails and it blocks them for you in the future, in a similar way as above.

Businesses – hardware and online filtering

If you are a business with a business-class firewall, a Spam filtering facility can be included in the appliance, depending on the hardware device chosen, so speak to your I.T. person about this.

There are also ‘Cloud’ solutions that can route emails from your email company through the Cloud filters before you even get them – there are many solutions to choose from.

Third Party Anti-Spam programs

There are a large number of ‘Anti-Spam’ programs which say that they help in blocking and removing Spam – they are essentially adding another filtering layer for your Inbox. Having said that, you do need to check for compatibility with your email program or app, so research is essential, especially as some of these programs are more reliable than others..

As with all things, make sure that you have regular backups, in case the worst happens, but if you do nothing else make sure that you mark your emails as Spam, before getting rid of them.

Microsoft Says Don’t Download Windows 10 Creators Update Yet

Windows 10 logo

Microsoft has advised users NOT to manually download the latest update to Windows 10 – called the Creators Update – but wait for it to be downloaded in the normal automatic update rollout instead.

Despite the massive publicity surrounding the latest Update release, they are finding issues with it particularly with older machines, such as some components no longer working after the Update has installed. This is why they are automatically updating newer machines first and hoping to identify and iron out bugs before the older systems get it during the normal course of events.

Even though Microsoft are deliberately rolling out the Update slowly, users can download the Creators Update themselves so Microsoft are worried that the issues that they have found will result in normal (e.g. non-geek) users having difficulties should they install the Creators Update before Microsoft want them to.

The Creators Update is the equivalent of an operating system upgrade (Windows 10.2 if you will) and it is a major undertaking even without the threat of parts of your machine not working afterwards. Certainly many of us in the I.T. world remember the problems caused by the last big Windows 10 update (the so-called ‘Anniversary Update’ last year) and even though we have learnt the hard way not to jump into the next ‘latest and greatest’ straight away (there are always bugs to be ironed out) it is surprising that they have asked users to stop manual updating so soon after release, so there must be further bugs that they are dealing with.

On the positive side at least Microsoft are warning people and not just releasing code that they know will cause problems to many people, although it is still a pity that testing didn’t show these issues before the Update was released to the public.

It also doesn’t help when you consider that Home and Small Business customers are effectively testing the Update before Enterprise customers get it, as it will not be released to the Enterprise sector for months – until the bugs have been ironed out.

If you have installed the Creators Update already, there is a way to uninstall it until it is more stable, although be aware that some apps/programs may be uninstalled in the process.Of course, as always, you should take a backup of your important files first just in case.

Go to Start > Settings and click ‘Update and Security’. Click on ‘Recovery’ > ‘Go back to an Earlier Build’ or depending on how long ago it was, click on ‘Go back to the previous version of Windows 10’.

If you are experiencing problems with Windows Update, give us a call on 01455 209505.
