Protecting your computer from viruses and malware is crucial. Here are five warnings your computer has a virus or malware and tips to help you avoid infections.

1. Sluggish response times, slow startup, and delayed operations could indicate a malware infection.

2. If you are experiencing an unusually high number of pop-up ads, especially ones that seem malicious or unrelated to the websites you are visiting, it could be a sign of malware.

3. Random system crashes, freezes, or unexpected errors may be indicative of malware interference.

4. If your internet usage is unusually high without apparent reason, it could suggest malware communicating with external servers.

5. Altered homepage, default search engine, or the appearance of unfamiliar toolbars in your web browser may be a sign of malware.

6. If you notice new or modified files, especially ones you didn't create or change, it could be a sign of malware activity.

7. Check for unauthorized or unexpected network connections, as malware often tries to communicate with command and control servers.
