Why does my computer freeze up every time i try to run a virus scan?

Answer 1

If you have Symantec Internet Security 2007 (or maybe just Norton Anti-Virus 2007), there is a bug.

My system was freezing too in Normal mode. They told me to run in Safe mode; it ran, but didn't check everything.

Finally I got a message that a new Vista compatible version fixed a bunch of bugs. I downloaded it (free), re-installed, and now the scan runs perfectly. (You do not need Vista for this fix.)

Good Luck

Violetto is right -- You could have too many applications running. Try rebooting (to clear your memory resource allocation, not necessary on most newer computers, but rebooting can help solve a lot of issues) and then run the virus scan with nothing else open/running.

Another problem could be that you already have a virus that is preventing your antivirus from running. Try downloading a free version of another antivirus and see if you can use it to clear up your system.
