I am reminded of the old saying "you get what you pay for". This product is gradually becoming a better performing and reliable av choice, but I wouldn't trust it at this point to protect my systems.
Sure, the price point is very inviting, but if it doesn't stop viruses I don't care if it is free.
Note: I base my opinion on
www.virusbulletin.com, where this product has twice as many fails as it does passes.
Normally, I wouldn't rip a free product, but stopping viruses is so important that I thought I would toss in my 2 pennies
