Source: Is antivirus software necessary in 2020?The perceived wisdom is that you should have antivirus software installed on your PC and an app of some kind on your mobile. Or that’s certainly been the case historically – if you don’t, the argument has always been that you’re running some major risks.
However, given advancements in operating systems and security in general, is this still true in 2020? Should you definitely be running antivirus software today? Or are there any good reasons why you might not want to?
Arguments against antivirus
The short answer to the titular question is: Yes, you should still be running some kind of antivirus software in 2020. It may even seem blatantly obvious to you that any PC user should be running an antivirus on Windows 10, but there are arguments against doing so. In some cases they’re not particularly valid ones, at least in our opinion, but they exist nonetheless.
One main pillar of the ‘anti-antivirus mindset’, as it were, is that if you’re sensible and careful enough about what you do online, only visiting legitimate websites, official software stores, and policing the links you click on with a suitable degree of vigilance, you probably won’t encounter any malware anyway.
And therefore the argument is you don’t need to pay for antivirus, and even if you install a third-party free antivirus app, it’s still another program on your system that might slow it down somewhat (some antivirus software can have more of an impact on system performance, and of course free software may also pop up ads and so on).
Another more pressing worry aired in recent times is that some of the antivirus software out there carries a number of vulnerabilities, and these could be a potential avenue of exploitation for an attacker. In other words, the potential irony is that your antivirus software could be an avenue for your machine to be compromised.
That’s a legitimate concern, as we’ve seen in recent times, when for example in March 2020, Avast disabled a major part of its antivirus software which suffered from a dangerous vulnerability that a respected security researcher flagged up.
So, as you can see, there are some gray areas when it comes to answering the question of whether you should run an antivirus. However, there are much stronger reasons as to why you should use an antivirus, which we’ll explore next.
