the new version AVG 8.0.138 is very nice, does not cause traffic to internet. its a nice upgrade. it really works fine now. slows has been reduce.
if we are going to compare avast 4.8 with avg 8.0 both paid versions
Avast 4.8 - has a lot of shield (web shield, standard, im, mail, p2p, script blocking, outlook)
AVG 8.0 - has resident shield and web shield only. (lacking of p2p is very important)
both are fine with me, but choosing what best for every pc is hard to do. AVG detections are much better than avast. and avast confirmed that they are not using heuristic analysis for their resident scanner, which i think is very important for resident scanner to have.
