How to Clean Malware from PC Windows 11/10 [2026]

Malware rarely shows itself directly, but the warning signs are hard to ignore, such as unexpected slowdowns, strange pop-ups, or programs you don’t remember installing. Once these issues start stacking up, it quickly turns from a minor annoyance into something that affects both performance and personal data safety. In cases like this, knowing how to clean malware from PC becomes essential. The following content focuses on clear ways to identify the problem and deal with it effectively.

Before learning how to remove suspicious programs or check for unusual activity, it helps to understand what malware actually is. Malware refers to malicious software designed to damage a system, steal information, or gain unauthorized access to a device. Common types of malware include:

• Virus: A type of malware that attaches itself to files or programs and spreads when those files are opened or shared.

• Trojan: A Trojan can create hidden backdoors, expose stored passwords, or allow attackers to gain remote control over the system.

• Ransomware: A threat that locks files or the entire system and demands payment to restore access.

• Spyware: Software that secretly monitors user activity, such as browsing habits, login credentials, or financial information.

Paying attention to unusual changes can make it easier to check for malware on PC devices before the problem becomes more serious.

• Unknown apps appearing: Programs you never installed may suddenly show up on the desktop, taskbar, or app list.

• Unusual data usage: A sudden spike in internet or background network activity can indicate malware sending data to external servers without permission.

• Constant pop-ups: Excessive ads, fake security alerts, or browsers opening random websites are common warning signs of adware or browser hijackers.

• Slow system performance: Slower-than-usual performance, especially during basic tasks, can be a warning sign that malware is quietly using up CPU, memory, or disk resources in the background.

Before trying to remove computer malware, it is important to isolate the system and inspect Windows carefully instead of deleting files randomly.

Step 1. Disconnect from the Internet

The first step is disconnecting the PC from the internet. This prevents malware from communicating with external servers, downloading additional threats, or sending out personal data. Turn off Wi-Fi, unplug the Ethernet cable, and disconnect unnecessary external devices.

Step 2. Enter Safe Mode to Check for Malware on PC

It is commonly used to check for malware on computer systems when normal scans fail or the PC becomes unstable.

For Windows 10 and Windows 11:

1. Open Settings > System > Recovery.

2. Under Advanced startup, select Restart now.

3. Go to Troubleshoot > Advanced options > Startup Settings on Windows PC. Click Restart.

4. Press 4 or F4 to enter Safe Mode.

Once inside Safe Mode, run Windows Security or another trusted antivirus tool to check for malware on PC devices thoroughly.

Step 3. Check Event Viewer to Find Malware on PC

Event Viewer can help identify suspicious actions linked to malware infections.

1. Type Event Viewer into the Windows search bar and launch the app.

2. Under Windows Logs, review categories such as System, Application, and Security.

3. Repeated error messages, failed login attempts, unknown processes, or unusual background activity may indicate hidden malware behavior. Reviewing these logs carefully can provide useful clues during the process of how to clean malware from PC systems safely and effectively.

Step 4. Download Professional Anti-Malware & Remove Computer Malware

While built-in Windows protection can detect many threats, deeper infections often require specialized software designed to remove hidden malware, spyware, ransomware, and browser-based attacks.

Step 5. Reset Browser & Restart
