avira is a great (prob the best in my opinion) for virus detection and protection, I'd also download malwarebytes (it's free) and ccleaner to keep your comp running up to speed.
Yeah i say you have enough security there....if you wanted to try better
security packages then i recommend Kaspersky Internet security 2010 or Eset Smart security.
They are both good,Probably the best paid for AV/Spyware packages out there.
thanks for your reply :good:, i'm thinking of purchasing a KIS 2010 maybe someday. right now i am currently using free avira anti-virus and zonealarm firewall
