Thanks so much for the help! I'll give avg repair a shot if this keeps going.

my AVG keeps telling me that Powershell.exe is behaving suspiciously and asking me if I should remove it or leave it. I keep telling it to remove it but whenever I start my computer it shows the same detection. Is this a false positive or is this possibly a much more serious problem that I have on my hands?
thanks in advance for any help
