Running a virus scan on Windows 11 is kinda like giving your PC a health check-up — you’re hoping it’s all good, but better safe than sorry. If your machine’s acting a bit off, slowing down unexpectedly, or you just want peace of mind, doing a quick scan with Windows Security is a good place to start. It’s built-in, dead easy to use, and most of the time, you don’t need to muck about with third-party software. That said, if you’re a bit of a download junkie or surf sketchy sites, sometimes Windows Security might not cut it. Still, for basic protection, it does the trick most of the time.
This guide’s all about showing you how to run a quick scan, do a deeper full scan, and some handy tips to keep your PC safe as houses. The idea? Catch any nasties early, see what’s going on, and steer clear of dramas. Turns out, with a few clicks, your PC can tell you if there are uninvited guests hiding around.
How to Scan for Viruses on Windows 11
Open Windows Security — The first step to peace of mind
Start by clicking the Start Menu, then typing Windows Security. On newer setups, it might be hiding under the Settings app, so you can also go there — Settings > Privacy & Security > Windows Security. Once you find it, open the app. It’s the built-in antivirus shield everyone forgets about until something feels a bit off. The interface is straightforward, but a bit clunky at times; Windows can make even easy stuff more complicated than it needs to be.
Navigate to Virus & Threat Protection — Find the magic button
Once inside, click on the “Virus & Threat Protection” section. This is basically your security dashboard. It shows your threat status, recent scans, and options for different scan types. If you see “Threats detected,” it’s a good idea to have a squiz. Sometimes it’s a false alarm, but better check everything before ignoring warnings.
Click on Quick Scan — Speedy detective work
Hit the Quick Scan button. This is what most folks do regularly — fast, doesn’t hog resources, and catches the usual suspects. It usually takes a few minutes, and sometimes it might hang or fail the first go, so don’t get your knickers in a knot. Just try it again if needed. The idea? It checks common hideouts for viruses, like your downloads folder, temp folders, and system files.
Review the scan results — What you see is what you get
Once finished, it’ll let you know if anything was found. If malware pops up, Windows Security will suggest what to do — quarantine, delete, or sometimes it’ll handle it automatically. Just follow what it says. Sometimes threats are false positives, so a quick Google search can help if you’re unsure. On one setup, it sorted itself out right away, but on another, I had to restart and run the scan again to be sure.
Run a Full Scan — Dig deeper if you need to
If you’re a bit paranoid or have had a run-in with infections before, a Full Scan’s worth doing. Go back to Scan options (click the button below the quick scan), then select Full Scan. It’s like a full-body MOT — slow but thorough. It checks every file and folder on your drive, just in case something sneaky slipped past the quick check. Expect it to take an hour or more, so best to do it when you’re not in a rush or working on other things.
Tips for Scanning for Viruses on Windows 11
- Keep Windows and Windows Security up to date. That way, you’re protected against the latest threats — because, let’s be honest, Windows can sometimes make simple stuff complicated.
- Set up regular scans — maybe schedule them at night or when you’re not even using the PC. The built-in scheduler works alright — just jump into Task Scheduler and set a task for Windows Security to run a scan.
- If you’re really worried about security, consider installing extra antivirus software. Just know that Windows Security might turn itself off when third-party antivirus is running — that’s normal.
- Check out the health reports in Windows Security — if there’s anything dodgy, even if no threats are flagged, it might give you a heads-up.
- And of course, be careful with downloads and links. If it looks dodgy, it probably is. Prevention beats cure, as they say.
Frequently Asked Questions
How often should I run virus scans?
Most folks do a quick check once a week, and maybe a full scan once a month, especially if they’re online a lot or dealing with downloads. Better safe than sorry, eh?
Can I run other antivirus programs alongside Windows Security?
Yeah, but it can be a tricky balancing act. Usually, Windows Security will turn off automatically when you install a third-party antivirus, just to avoid conflicts. Just make sure whatever you use is legit and kept up to date.
What if a virus gets flagged?
If Windows Security finds something, just follow its prompts. Usually, it’ll quarantine or get rid of the bad stuff. Sometimes you’ll need to restart your PC — a bit of a pain, but that’s how it rolls sometimes.
Is Windows Security enough?
For most people, yeah. But if you’re browsing dodgy sites or downloading heaps of shady files, it might be worth considering extra protection. No security tool’s perfect, especially these days.
How do I keep Windows Security current?
Make sure automatic updates are on under Settings > Update & Security > Windows Update. Windows Security updates itself pretty often — half the battle’s keeping it up to date.
Summary
- Open Windows Security.
- Go to Virus & Threat Protection.

- Keep everything up to date and set regular scans.
Wrap-up
Running virus scans might seem a bit of a chore, but it’s a small price for peace of mind. One machine I use, a quick scan caught a nasty bug last week, and on another, I had to run a full scan to find a sneaky infection. Sometimes, Windows Security throws up false alarms — no worries if it does, just double-check. All in all, these steps are usually enough to keep most rubbish at bay — at least for a while. Hope this helps someone avoid ranting at a frozen or wonky PC over malware!
