You may not be all that worried about computer viruses. You might think since you stick to safe websites and don't download anything except legal software from legitimate sites that you're safe.

Unfortunately, even if you're not the weak link in the security chain, you can't trust legitimate websites to have perfect security - they may be hacked and their site compromised.

These days, viruses won't do relatively harmless things like displaying unwanted adverts: they can cost you dearly.

They can install keyloggers which can steal your personal information, especially your credit card or bank details. On the other hand, you might be tricked into typing your details into a fake website and it's this kind of threat that modern security suites protect against.

They provide all-round protection that you need to keep your data safe no matter which device or what app or web browser you're using.

From worms and Trojans to ransomware and phishing scams, good antivirus can prevent them all. So it's worth having the best you can get.

Put simply, antivirus software isn't optional. The risk of your computer becoming infected with something nasty is simply too great not to run it.

Fortunately, you don't have to pay full price as we've rounded up the best discounts to be found this month.

Antivirus deals: What to look for

Antivirus software detects, and then prevents, disarms or removes malicious programs and malware, often referred to as ‘viruses’. But as we've said, security software is no longer just about countering viruses. It's also about the security of personal data and protection from ransomware.

Check that the antivirus software you’re buying has ransomware protection built-in, and it’s also worth looking out for the ability to detect malware is so new that it hasn’t yet been analysed by security companies. This may be bolstered by a cloud element or artificial intelligence, which can really help to ensure that even the most sophisticated attacks get nowhere near your devices.

Antivirus discounts are plentiful, often with more than 50% off for your Mac, PC or mobile device. Sometimes these discounts are available on the websites of the antivirus providers themselves in the form of a digital download, but you can also find cheap boxed versions of the software from the likes of Amazon, Argos and Currys PC World.
