Searching "Windows Defender" in the Get-go carte du jour volition bring up Windows Security, and even now, Microsoft often refers to its actual antivirus scanning as Windows Defender.

Microsoft's built-in anti-malware software used to be thought of every bit totally worthless, but these days, it can hang with large names like Kaspersky and Avast in independent tests (blocking 99.7% of threats). Microsoft has also been pushing security with Windows 11, even going so far equally to confusingly lock out people with older computers that don't take certain hardware.

What are the signs my PC is infected?

Malware comes in many shapes and forms, simply there are some common things it may do to your computer. If you notice that your search engine, browser homepage, or even desktop wallpaper accept changed without you doing anything, it may be fourth dimension to run a scan as described above. Other symptoms could be your computer running hotter or slower than usual or seeing popups or notifications that yous haven't seen before.

Google has a smashing video describing some of the mutual symptoms of malware.

If Windows detects a threat

If you lot go a notification from the Microsoft Security app saying that it's detected a threat, it's likely that the problem has already been dealt with. However, it is worth double-checking the notification — some malware (especially malicious web ads) will pretend to exist an antivirus notification to get you to click on them.

Windows Security notifications volition expect like the image shown below and will appear on the top right corner of your screen. Later on they disappear, they'll be shown on the notification screen, which you lot can view by clicking on the clock in your taskbar.

*An instance of the notification you'll get if Windows Security finds a suspicious file.*

Whitelisting a file

While anti-malware software tries its best to only flag the bad files and leave the good ones, sometimes it will become information technology wrong. If you're very sure that Windows has made a error and deleted a file that it shouldn't accept, you can recollect information technology.

Earlier you practise so, it'southward worth noting that merely considering y'all trust the person who sent you a file does not mean that the file is safe. In that location is some malware that is able to hijack people's emails and send copies to anybody in their contacts. If you receive a suspicious file from someone you trust, it's a expert thought to ask them about information technology before trying to open it.

*The Protection history screen volition show you lot the incidents Windows Security has monitored.*

To view and restore an incorrectly flagged file, go to "Windows Security" > "Virus and threat protection" > "Protection history." There you'll detect whatsoever threats that Windows Security institute, along with their severity level. To restore a file (which, again, yous should be very conscientious before doing), click on the entry, then click the "Deportment" button to get access to the "Let" button.

*The Protection history screen can give you details near a detected virus, such every bit where it was constitute, and what type of malware it is.*

What happens afterwards you allow the file depends on how it was dealt with. If its status is "Quarantined," assuasive it will put it back on your computer. If its status is "Removed," y'all'll accept to download information technology again, but Microsoft Security won't finish yous.

You tin can view a list of the detected files you've allowed by going to "Windows Security" > "Virus & threat protection" > "Allowed threats." If you've decided they are indeed a threat, you tin re-delete them by clicking on them, so clicking the "Don't permit" button.

When things go nasty

Sometimes in that location are viruses or pieces of malware that fight back when y'all try to remove them. To help deal with this, Windows has a sort of extra-force version of its antivirus scan. To run information technology, get to "Windows Security" > "Virus & threat protection" > "Scan options," and select "Microsoft Defender Offline scan." Subsequently clicking the "Scan now" push, your computer will restart into a special manner to do a browse. Once it's done, your computer will restart again, bringing yous dorsum to Windows.

If your estimator still shows signs of being infected, some of us here at The Verge recommend the free version of Malwarebytes, which has saved our (and our relatives') machines more than than a few times. (It's a good thought to have Malwarebytes already on your computer since some malware can block you from installing whatsoever additional security apps.)

If your PC is still locked up, or you're suddenly getting notifications that y'all need to send somebody money to unlock it, information technology may exist fourth dimension to contact an IT professional.

Third-party anti-malware apps

While Windows Security should exercise a expert chore at protecting your figurer from viruses, malware, and other nasty files, there are yet things it can't do — for instance, fifty-fifty with Windows eleven, the built-in tools won't protect you from electronic mail phishing scams or from scam ads in your web browser.

If you're looking to step up your game from the basic Windows Security, you might want to cheque out anti-malware suites, such every bit McAfee, Norton 360, Kaspersky or Bitdefender. Searching out a few reviews will give you a good idea of what you need (and what yous don't — looking at you, programs that come up with crypto miners).

If you've heard virtually the dangers of running multiple anti-malware systems, don't worry; Microsoft says its built-in solution will automatically turn off if information technology detects that in that location's another antivirus installed and activated. If you uninstall the other anti-malware app, Microsoft's should plow back on automatically.
