Figuring out if your Windows 11 machine has been hacked is kind of weird, but it’s definitely a skill worth having. Some signs are subtle, like weird network activity, unfamiliar programs popping up, or security settings that seem off. Because Windows doesn’t exactly make this obvious, it’s good to walk through some practical steps to catch any potential intrusions early. Maybe you’re just paranoid, or maybe there’s a real threat — in either case, knowing what to check can save you a headache down the line, especially if someone’s been messing around with your stuff.
How to Tell If Your Computer Has Been Hacked on Windows 11
Follow these steps if you suspect that your system might have been compromised. They’ll help you spot the red flags and get a clearer picture of what’s going on behind the scenes. Remember, it’s not always obvious — sometimes malware hides pretty well, and hackers are getting sneakier. But these checks can point you in the right direction and help decide if it’s time to take more serious action.
Check for Unusual High Network Activity
Open Task Manager (press Ctrl + Shift + Esc or right-click the taskbar and choose Task Manager).Go to the Performance tab, then click on Wi-Fi or Ethernet. Watch your network usage. If your network isn’t doing anything heavy but the meter is climbing for no reason, it might be someone stealthily lurking, sending or receiving data without your knowledge.
This is especially suspicious if you notice sustained high activity over a long period or at odd hours. Sometimes, malware piggybacks on your network to exfiltrate data or do some sneaky mining. Keep an eye on it.
Note: On some setups, this appears to work the first time, then sometimes it takes a reboot or a quick network reset to get accurate readings. Windows can be weird with these stats.
Look for Suspicious Programs
Still in Task Manager, go to the Processes tab. Scroll through and see if anything looks shady or unfamiliar. You might see stuff with strange names or processes you didn’t install. Sometimes malware disguises itself as legitimate apps or runs in the background without obvious signs.
Right-click any suspicious process and choose Open file location. If the location isn’t in a usual system folder (like C:\Program Files or System32), that’s a red flag. Do some quick googling to see if others report that app as malicious.
This isn’t foolproof — malware authors get clever, but it’s a decent start, especially if something wasn’t there before.
Review Security Settings
Open Windows Security by search or via Settings > Privacy & security > Windows Security. Check that Virus & threat protection is enabled and up-to-date. Click on Virus & threat protection updates and hit Check for updates.
If you see that some security features are turned off, especially without your action, it could mean someone tried to weaken your defenses. Also, review the Device Security and Account Security sections for anything out of the ordinary.
On some systems, a hacker disables security tools to avoid detection, so don’t dismiss this check — it’s a common move.
Check for Unknown User Accounts
Go to Settings > Accounts > Family & other users and look at the list of accounts. Do you see any that shouldn’t be there? Accounts you didn’t create or authorize are a sure sign of trouble.
Sometimes hackers create hidden accounts for easy future access. If you see anything suspicious, delete or disable it — but remember, making changes here might lock you out if you’re not careful. Better to research first or create a backup.
Run a Malware Scan
The last line of defense is a full malware scan. Use Windows Defender, which is built-in, or a trusted third-party antivirus like Malwarebytes (make sure it’s up-to-date).In Windows Security, click Virus & threat protection, then hit Run a new scan and select Full scan.
This process can take a while, but it’s the most reliable way to catch anything nasty hiding around. Sometimes, you run the scan, and it finds threats you didn’t know about. Other times, it comes back clean but you still have suspicions — better safe than sorry.
After these steps, your system should be clearer, but remember — malware can be sneaky, and new threats pop up all the time. Regular checks, updates, and good security habits are the best prevention.

Frequently Asked Questions
How do I know if my computer is hacked?
If it’s acting weird — unexplained network spikes, new programs, weird security settings, unknown user accounts, or it keeps crashing — it might be compromised.
What should I do if I suspect my computer has been hacked?
Disconnect from the internet first—unplug the Ethernet or turn off Wi-Fi. Then run a full malware scan, check for unfamiliar programs or accounts, and change passwords for your important accounts.
Can antivirus software prevent hacking?
It helps, but it’s not a magic shield. Malware can slip through, so keep your system updated and practice safe browsing. That’s the real defense.
How often should I scan for malware?
Once a week is good, especially if you’re downloading files or visiting sketchy sites. More often if things seem off.
Is Windows 11 more secure than older Windows versions?
It does have some security improvements, but no OS is perfect. Staying cautious online and keeping things updated is still key.
Summary
- Check your network activity for weird spikes.
