Has any one used the defender pro anti virus software? if so do you likeit?

It has good detection rates, it doesn't use many resources but it isn't very good at detecting spyware, though things may have changed in the latest version which I didn't try it yet.

Still I would go either for Kaspersky or Esset's Nod32 if you intend to buy an antivirus.

Of course there's also freeware alternative like Avast or Avira. Not the same features but it will keep you protected from viruses.

Kaspersky is the best I have used.I have used Norton,Defender and others.Do not waste your money on Norton. Kaspersky has extra good features.
