The Antivirus Software Myths I Keep Correcting

Why Antivirus Still Confuses So Many People

Antivirus software has been around since before most of us had home computers, yet it's still one of the most misunderstood tools in anyone's digital toolkit. Clients tell me they've either given up on it entirely because "it slows everything down" or they think one program installed years ago is quietly protecting them forever. Neither is true. Antivirus software is a genuinely useful layer of protection, but only if you understand what it actually does and, just as importantly, what it doesn't.

Myth: Antivirus Alone Keeps You Completely Safe

This is the myth that worries me most because it breeds a false sense of security. Antivirus software is brilliant at catching known malware and suspicious file behaviour, but it can't stop you from typing your password into a convincing fake login page, and it won't warn you that the urgent email from your bank is actually a phishing attempt. Think of it as one guard on the door, not the whole security system. You still need good habits alongside it, including strong unique passwords stored in a password manager and two factor authentication on anything that matters.

Myth: Free Antivirus Is Just as Good as Paid

Free antivirus tools aren't useless, and something is usually better than nothing. But most free versions strip out real time protection or regular updates in favour of the paid tier, and some fund themselves by collecting and selling your browsing data, which rather defeats the point of using security software in the first place. If you're relying on a free tool, at least know what it's leaving out so you're not caught assuming you're covered when you're not.

Myth: Antivirus Slows Your Computer Down Too Much to Bother

This one was true a decade ago and it's the reason so many people switched theirs off and never turned it back on. Modern antivirus software runs quietly in the background and barely touches performance on anything built in the last few years. If yours is genuinely grinding your machine to a halt, it's usually a sign the software is outdated, poorly configured, or fighting with another security tool you've also got installed, not that antivirus itself is the problem.

What I Actually Look For in Antivirus Software

I want real time scanning, automatic updates, decent ransomware protection, and a company with a solid track record rather than the cheapest name I've never heard of. I also want it working alongside the rest of my setup, a VPN when I'm on public wifi and two factor authentication everywhere it's offered. None of these tools do the whole job alone. If you want a look at exactly what I use and recommend, my Safety Toolkit page has the lot laid out in one place. And if you're not sure whether your current setup is doing enough, get in touch and I'll take a look.
