I did run Avira briefly a year or two back, but found it didn't detect anything that AVG couldn't. No worse, but no better... I may well be wrong though?
I thought a switch to a paid AV would be worthwhile given the amount of "risky" browsing I did... worst decision I ever made. BitDefender seemed to have mostly good reviews, but I've had nothing but trouble with it, numerous bugs, no customer support and protection not much better than any of the free ones. And the number of times I've lost that protection and needed to cleanly reinstall beggars belief - on my laptop (running Vista) it has never lasted 3 weeks without developing a fault of some sort.
I was considering NOD32 for my new system - do you think Avira and saving the money would be a better option?
