Different viruses will affect your computer in different ways. The symptoms are specific to the virus. Viruses are capable of:
- deleting files
- preventing you from rebooting your computer
- sending emails from your account without your knowledge
- making your computer run more slowly
- holding files hostage
- hacking your computer cam
- exposing your personal information (for example, payment data)
Even if a virus causes no obvious problems on your computer, you may inadvertently spread it to someone else who is vulnerable. The best way to combat viruses is to take precautions to reduce your risk of infection in the first place.
