Avast and Avira are the other freebies. Try them. Avast uses less RAM so should be quicker.</p> </p> Edit - Comodo now do a free one too. Not got any stats on how it compares speed or security wise but it's worth a look </p>
My Network Backup went from 9 Hours to 15+ Hours That was after upgrading from AVG 7.x => 8.5. It's no longer "overnight" by any stretch of the imagination. I logged a call with AVG, but so far I'm not best pleased with them...
