Antivirus software program is an important piece of safety on any Windows PC. On an web the place malware is simply changing into increasingly more worthwhile for organized crime, you don’t wish to be and not using a good antivirus program.
But there are a variety of myths floating round on the market about antivirus software program. Let’s bust them.
Myth: You want to put in antivirus on Windows
You don’t have to put in antivirus software program on Windows as a result of Windows already comes with antivirus software. In truth, Windows has had built-in antivirus software program since Windows 8, and it’s nonetheless included on Windows 10 and Windows 11 as we speak. The built-in Microsoft Defender antivirus is a part of the Windows Security suite of tools. It’s as primary because it comes, however utterly free and runs mechanically within the background, even in the event you by no means take into consideration or set up antivirus software program.
Now, chances are you’ll want one other antivirus — different antiviruses have additional instruments, safety options, and choices, and so they use completely different detection engines. But the excellent news is that each Windows PC has a baseline antivirus package deal. We’re long gone the times of Windows 7, Windows Vista, and Windows XP nagging you to put in antivirus software program once you arrange a brand new PC.
Microsoft’s antivirus will get out of the way in which when it must, mechanically disabling its computerized background scanning options in the event you select to put in a third-party antivirus. You simply don’t have to consider it.
Myth: Only Windows is weak to malware
Malware (together with viruses, Trojans, worms, rootkits, ransomware, and every kind of different appalling issues) is an issue on all platforms.
Yes, even Linux is weak to malware threats — simply take a look at the recent XZ Utils backdoor saga that just about noticed a rootkit slipped right into a essential piece of open-source software program. Or, think about the Linux distribution Ubuntu labeling a malicious app that stole people’s cryptocurrency as “safe.” Linux malware typically targets server software, as Linux is a lot extra well-liked in information facilities than on the desktop.
I’m not making an attempt to single out Linux right here! The actuality is that malicious software program is an issue on all platforms — even Linux. No platform is above the fray.
People could say Macs don’t want antivirus, however Apple truly has an antivirus-style system constructed into macOS. It’s named XProtect. Various corporations additionally make antivirus programs for Macs.

Myth: Antivirus will decelerate your PC dramatically
Antivirus software program runs within the background, scanning information once you obtain them and earlier than you open them. Before an utility launches, your antivirus offers it a fast examine and warns you if it seems to be malicious.
Now, clearly this can use some system assets. Your PC is doing a bit of additional work. But we’re not within the ‘90s or early ‘00s anymore. Back then, PCs have been a lot slower. Antivirus software program simply felt so heavy to make use of, and you might really feel it slowing down your PC at instances. I bear in mind it properly! But that was way back.
Modern antivirus functions shouldn’t gradual your PC down in a noticeable means. If it takes 2 % longer to launch an utility, will you discover? Not actually. Those shouldn’t be fixed slowdowns, both — they need to happen once you launch an utility and the antivirus is checking it out, not on a regular basis when you do issues in your PC.
Plus, until you’ve gone out of your option to disable its background scanning (I like to recommend towards it!), Microsoft’s Defender antivirus is already operating within the background in your PC, scanning for malware. When we benchmark PCs here at PCWorld, we go away the usual Defender antivirus operating. So, even in the event you selected to swap out the built-in Defender antivirus for one more antivirus, you’d simply be buying and selling one antivirus for one more — not including an additional efficiency price on prime.
In some instances, antivirus software program could decelerate a workload: If you’re compiling software program, for instance, and you’ve got a folder the place a lot of information are being created, chances are you’ll wish to merely “exclude” such a folder out of your antivirus’s scanning. That’s probably the most you need to have to do.
When antiviruses carry out their heavy full-system scans, that can undoubtedly gradual issues down additional whereas they’re operating. But these scans are normally scheduled to occur when you’re not utilizing your PC. You shouldn’t discover them in any respect.
Myth: You need to run antivirus software program manually
There’s no have to commonly open your antivirus program, click on the “Scan” button, and look ahead to the outcomes. Your antivirus is mechanically scanning within the background to guard you, checking information once you obtain and launch them. It’s additionally performing this sort of complete system scan on a schedule — within the background — once you aren’t utilizing your PC. Your antivirus will let you recognize if it finds as downside.
Windows Security is all the time operating within the background on a contemporary Windows PC — until you put in one other antivirus.

Save your self the difficulty and keep away from the time-consuming handbook scans — until you’re involved your system may need malware and also you wish to examine all of the information in your PC’s storage proper now. Scanning like this is only one of many outdated security practices you no longer need to follow.
Myth: Antivirus will shield you from all threats
Antivirus software program isn’t utterly good. Now, I do know that is form of an apparent assertion. But I’ve seen many individuals act like antivirus will present them good safety and run into hassle.
You ought to consider your antivirus software program as a final line of protection. If all of your regular safety precautions fail or an utility you utilize has a harmful zero-day flaw that lets an attacker achieve entry to your PC, your antivirus program is there to choose up the slack and cease malware from operating.
But it’s not good. Antivirus software program catches malware in a number of methods. For instance, it appears to be like for known-dangerous utility information — packages which have been seen earlier than that the antivirus is aware of is unhealthy — and makes use of heuristics to aim to guess whether or not a newly seen file is harmful or not. Neither methodology will catch every little thing. And Windows Security doesn’t even attempt to shield customers from phishing electronic mail assaults or browsing probably harmful web sites (although many premium AV suites off this).
While antivirus is a crucial layer of safety, it’s not a good suggestion to rely completely on it. In explicit, it’s an especially unhealthy concept to pirate software program and video games — in the event you’re operating pirated utility information, cracks, key mills, and comparable sketchy issues, you’re exposing your self to a lot of potentially dangerous things. Antivirus isn’t assured to guard you from all of them.
Myth: You don’t want antivirus in the event you’re cautious
On the opposite hand, some individuals assume antivirus is simply essential for less-experienced laptop customers with out ultimate safety practices. The concept is that, in the event you’re cautious and sensible, you possibly can skip the antivirus and get again that little little bit of efficiency.
But this isn’t actually true. Malware isn’t simply one thing you get contaminated with once you’re not cautious. Attackers can exploit zero-days in functions you utilize, and you might be contaminated just by viewing a compromised net web page. All it will take is the proper flaw in your net browser.

The Downfall mod for Slay the Spire was compromised and used to unfold malware via Steam’s software program replace system.

Also, check out Steam: Steam developer accounts have not too long ago been compromised and used to serve malware through Steam game updates — and mod updates. Hopefully Steam’s replace system gained’t ship malware to your PC, but it surely illustrates that it doesn’t simply matter how cautious you’re. A stable antivirus may present a very good layer of safety towards assaults like this.
Myth: Antivirus will utterly shield you
Antivirus isn’t all you have to shield your self — and your PC — on-line. It’s an necessary a part of the puzzle, however you want greater than that.
Scam web sites and phishing emails are harmful on each machine — not simply Windows PCs, but additionally smartphones. You nonetheless have to browse fastidiously, hold a watch out for scammy-seeming emails, keep away from downloading harmful junk, and never get tricked into giving passwords, cost information, and different private particulars to unhealthy web sites. Antivirus packages and net browsers do have phishing safety — however, like antivirus scanners, it isn’t good.
A good password manager is especially necessary. Using sturdy, distinctive passwords all over the place is critically necessary. But, until you’ve gotten a photographic reminiscence, you’re most likely not going to recollect dozens (or a whole lot) of sturdy distinctive passwords for all of your accounts. A superb password supervisor is the answer to maintain your accounts safe.
By the way in which, even in the event you do set up one other antivirus in your Windows 11 or Windows 10 PC, you don’t need to pay for one. There are great free antivirus programs you possibly can set up in the event you’re not trying to pay for one among PCWorld’s favorite antivirus programs, although the premium variations have a tendency to guard towards extra varieties of threats (akin to malicious hyperlinks, webcam hacks, and privateness monitoring) and supply further options (like VPNs and parental controls).
