While McAfee receives more user complaints about being cumbersome and hogging system resources than any other product other than Norton/Symantec,.... AVG is rapidly approaching the same frequency of dissatisfaction amongst users (more due to poor updating, but also because of growth in size and tendency to hog resources... thereby slowing down speed of computer function.
I personally use Avira AntiVirus
More of our Techs tend to recommend AVAST! AntiVirus
Some folks like to use McAfee Site Advisor
to give them Website ratings when they search/browse. (even though they don't use the rest of McAfee)
McAfee Site Advisor is available (free) http://home.mcafee.c...ces.aspx?ctst=1
I chose not to use anything of McAfee and instead have subscribed to the excellent Web Of Trust (WOT)
Web of Trust
is available (free) http://www.mywot.com/
Please also give your attention to AntiSpyware and Firwall consideration.
