Kaspersky 8.0 v AVG free edition,any thoughts ?
There's a difference between free and paid. The speed of response.
There is no incentive for the free commmunity to provide rapid updates to cover new viruses (which appear more frequently than you may think !). The commercial guys have every incentive, if they are slow, people go to a competitor.
Kaspersky and F-Secure are rumored to be some of the quickest in the business.
F-Secure are good because they have multiple engines , and so more chance of finding stuff (one of their engines is Kapersky, funnily enough).
