Antivirus software program is a vital piece of safety on any Windows PC. On an web the place malware is barely turning into an increasing number of worthwhile for organized crime, you don’t wish to be and not using a good antivirus program.
But there are numerous 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 at the moment. The built-in Microsoft Defender antivirus is a part of the Windows Security suite of tools. It’s as fundamental because it comes, however utterly free and runs mechanically within the background, even should you by no means take into consideration or set up antivirus software program.
Now, it’s possible you’ll favor one other antivirus — different antiviruses have additional instruments, safety options, and choices, and so they use totally 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 if you arrange a brand new PC.
Microsoft’s antivirus will get out of the way in which when it must, mechanically disabling its automated background scanning options should 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 vital 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 in style 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 might say Macs don’t want antivirus, however Apple truly has an antivirus-style system constructed into macOS. It’s named XProtect. Various firms additionally make antivirus programs for Macs.

Myth: Antivirus will decelerate your PC dramatically
Antivirus software program runs within the background, scanning recordsdata if you obtain them and earlier than you open them. Before an utility launches, your antivirus provides it a fast verify 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 could possibly really feel it slowing down your PC at occasions. I keep in mind it effectively! But that was way back.
Modern antivirus functions shouldn’t gradual your PC down in a noticeable manner. If it takes 2 p.c longer to launch an utility, will you discover? Not actually. Those shouldn’t be fixed slowdowns, both — they need to happen if 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 method to disable its background scanning (I like to recommend in opposition to 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 depart the usual Defender antivirus operating. So, even should 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 value on high.
In some instances, antivirus software program might decelerate a workload: If you’re compiling software program, for instance, and you’ve got a folder the place numerous recordsdata are being created, it’s possible you’ll wish to merely “exclude” such a folder out of your antivirus’s scanning. That’s probably the most you must must do.
When antiviruses carry out their heavy full-system scans, that can positively 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 must usually open your antivirus program, click on the “Scan” button, and watch for the outcomes. Your antivirus is mechanically scanning within the background to guard you, checking recordsdata if you obtain and launch them. It’s additionally performing one of these complete system scan on a schedule — within the background — if you aren’t utilizing your PC. Your antivirus will let if it finds as drawback.
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 guide scans — until you’re involved your system might need malware and also you wish to verify all of the recordsdata 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 defend you from all threats
Antivirus software program isn’t utterly good. Now, I do know that is type 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 seems to be for known-dangerous utility recordsdata — applications which were seen earlier than that the antivirus is aware of is dangerous — and makes use of heuristics to try to guess whether or not a newly seen file is harmful or not. Neither methodology will catch every thing. And Windows Security doesn’t even attempt to defend customers from phishing e-mail assaults or browsing doubtlessly 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 specific, it’s a particularly dangerous thought to pirate software program and video games — should you’re operating pirated utility recordsdata, cracks, key turbines, and related 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 should you’re cautious
On the opposite hand, some individuals suppose antivirus is barely obligatory for less-experienced pc customers with out ultimate safety practices. The thought is that, should you’re cautious and good, 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 if you’re not cautious. Attackers can exploit zero-days in functions you utilize, and you could possibly be contaminated just by viewing a compromised internet web page. All it could take is the precise flaw in your internet browser.
The Downfall mod for Slay the Spire was compromised and used to unfold malware by way of Steam’s software program replace system.

Also, check out Steam: Steam developer accounts have lately been compromised and used to serve malware through Steam game updates — and mod updates. Hopefully Steam’s replace system received’t ship malware to your PC, nevertheless it illustrates that it doesn’t simply matter how cautious you might be. A stable antivirus may present layer of safety in opposition to assaults like this.
Myth: Antivirus will utterly defend you
Antivirus isn’t all you’ll want to defend 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 system — not simply Windows PCs, but in addition smartphones. You nonetheless must browse rigorously, hold an eye fixed out for scammy-seeming emails, keep away from downloading harmful junk, and never get tricked into giving passwords, cost data, and different private particulars to dangerous web sites. Antivirus applications and internet browsers do have phishing safety — however, like antivirus scanners, it isn’t good.
A good password manager is especially necessary. Using robust, distinctive passwords in all places is critically necessary. But, until you will have a photographic reminiscence, you’re in all probability not going to recollect dozens (or a whole lot) of robust distinctive passwords for all of your accounts. A very good password supervisor is the answer to maintain your accounts safe.
By the way in which, even should 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 should you’re not seeking to pay for considered one of PCWorld’s favorite antivirus programs, although the premium variations have a tendency to guard in opposition to extra sorts of threats (comparable to malicious hyperlinks, webcam hacks, and privateness monitoring) and provide further options (like VPNs and parental controls).
