Can I install more than one anti-virus program on my computer and will both work?
www.grisoft.com and download the free AVG anti virus. You only need one. Downloading two will almost certainly cause it to crash. However, just because your computer is crashing, doesn’t mean it’s a virus – it could be but it could be something else. You could have more than one anti spyware program running which could be causing it to crash. Try deleting all of the non essential programs off including anti spyware. They could be conflicting with each other.
