Malware can steal your data, slow down your computer, or damage important files. Below are the most common signs of an infection and what you can do to fix it.

1. Your Device Becomes Extremely Slow

Malware often runs in the background and uses system resources.

• High CPU or memory usage
• Programs take longer to open

2. You See Random Pop-Ups or Ads

Pop-ups appearing unexpectedly can indicate adware or malicious software.

• Ads show even when no browser is open
• Frequent redirects or interruptions

3. Programs Install Themselves

If you see apps you don’t remember installing, they may be unwanted or malicious.

• Toolbars
• “Cleaner” apps
• Unknown software

4. Browser Homepage or Search Engine Changes

This is a common sign of browser hijacking.

• Default homepage changes
• Search results redirect to unknown sites

5. Files Disappear or Get Renamed

Missing or renamed files may indicate ransomware or file corruption.

6. Your Accounts Show Suspicious Activity

If your accounts are compromised, malware may be involved.

• Emails sent without your knowledge
• Password resets you didn’t request

7. Your Computer Crashes or Overheats

Malware can run heavy processes in the background.

• Frequent crashes
