Recognize a Computer Virus Infection
1. Check your hard drive activity.
2. Note how long it takes your computer to boot.
3. Make note of program crashes. If it happens often, it may be infected.
4. Look for random popups and disappearing files.
5. Check your web browser for irregular activity.
6. Try opening the Task Manager. A virus may prevent you from opening it.
