[Kastersky Internet Security makes my PC shut down if I run a scan. [Closed]]

I just got [another AV] instead. I can now do scans without my PC getting shut down. It seems like a much better and smoother program.

[Kastersky Internet Security makes my PC shut down if I run a scan. [Closed]]

About a week ago I formated my PC, installed Windows 7, then installed all the Windows Updates, then installed drivers, then installed Kaspersky Internet Security Trail. I thinking of buying this program, but whenver I run a scan, my PC gets shut down mid way through scan. This is very bad, please help me. Or would I just be better off uninstalling and finding another anti virus?
