Low Performance: If your computer suddenly starts running much slower, it is possible that malware is using your system’s resources. First, rule out basic causes such as too many applications or outdated software.
Pop-up Windows: Unexpected ads or warnings about “crimes” are a classic trick of malicious programs. Never click on them.
Unknown Applications: Check your device for unfamiliar programs. They may be disguising malware.
Browser Changes: If your homepage or search engine switches on its own, this could also be related to viruses. Restart your browser and remove suspicious extensions.
Firewall Disabled: A disabled firewall may indicate that malware is hiding its activity. Check the settings to reactivate it and save your PC.
High Data Usage: Sudden spikes in internet consumption may mean that malware is sending your information elsewhere. Use Task Manager or Activity Monitor to check.
Do not rely solely on free antivirus programs. Update your system, use reliable programs, and regularly check for unusual activity to prevent viruses.
