Hi... My nephew is a college student and needs to put virus protection on his PC. He asked for my advice. My problem is I use Mac so I don't mess with any Virus protectors. For you PC experts out there, which one would you suggest that is: 1) Cheap...he is a college student. Free would be great. 2) Easy...not a computer expert. 3) Won't gunk up and slow his computer down. Any suggestions would be great. I know there is more economical solutions out there other than Norton and McAfee.
