Just a caution about running 2 antivirus programs at once... I ran McAfee and Norton, thinking I would be doubly safe, but the two interfered with each other and I ended up with over a 1000 virus variations on my machine. The tech told me that and I couldn't believe it! I still think he was exaggerating. But even after F disking the original hard drive, I never got rid of everything and found the drive filling faster than it should. So I now have one new hard drive and am sticking with Norton Antivirus.
