How to stop a cyber attack on your PC

The internet is littered with digital threats – and the recent cyber attack on the NHS proves that every computer is at risk from viruses.

“Widespread cyber attacks like this one make consumers worry about their own online security,” says Alex Neill, Which? Managing Director of Home Products and Services.

“The Government currently doesn’t think patient data has been accessed, but if you are concerned, there are things you can do to try and protect yourself from fraud,” says Alex.

Prevention is always better than cure, so if you’re not already keeping a close eye on your machine as a result of the global cyber attack, follow these four simple rules to keeping your computer safe.

Buy security software

Whether you’ve got a Mac or a PC, it’s a no-brainer to have proper internet security. Norton, Kaspersky, ESET, Bitdefender and McAfee are recognised as the top five antivirus software on the market. They’ll fight off viruses and keep your computer protected for a charge of around £50.00 for a yearly subscription.

Download a firewall

Third party security software, such as firewall and anti-spyware, can often be downloaded free of charge and will provide extra protection for your computer alongside your chosen security software.

Like antivirus software, it runs in the background at all times and it’ll create an extra barrier between your computer and any online threats.

There are many excellent, free systems on the market – so try ZoneAlarm Free Firewall, Comodo Free Firewall or PeerBlock to give your computer added protection.

Accept updates

Although they can be annoying, software updates are vital to the health of your computer.

Always accept the update to keep your security at the highest possible level.

Use your common sense

Remember, if it looks dodgy then it probably is. Beware of spam emails, unwanted pop-ups and pirate sites.

Never download anything which you’re not 100 per cent sure about, and that will help to keep your computer clean.
