These threats can compromise your computer’s performance, steal personal information, and cause significant damage. Understanding the different types of malware can help you identify and remove them effectively.
How to Detect Malware on Your PC?
Detecting malware involves recognizing unusual behavior on your computer, such as slow performance, unexpected pop-ups, or unauthorized changes to settings. Use the following steps to confirm the presence of malware:

Steps to Completely Remove Malware from Your PC
1. Back Up Important Data
Before removing malware, ensure you back up important files to an external drive or cloud storage. This precaution protects your data in case of accidental loss during the cleanup process.

Disconnecting from the internet prevents malware from communicating with external servers or spreading further. This step is crucial to contain the threat while you work on removing it.

- Restart your computer.
