What Are the Signs of Malware on Your PC?
Recognizing the symptoms of malware is the first step in protecting your PC. Common indicators include:

- Frequent Crashes: Unexpected shutdowns or frequent crashes can signal malicious software interference.
- Pop-Ups and Ads: An increase in unwanted pop-ups or ads, especially when offline, can indicate adware.
- Unusual Network Activity: High data usage or unknown programs accessing the internet might be signs of spyware.
