I have been using Nod32 for nearly 2 years now. However it still has incompatibilities with Firefox which have never been fixed: Downloads freeze, tried the disable scan thing in about:config. Every single large download freezes up my browser. This has been the same through multiple systems. From desktop to laptop. Starting a cold boot firefox causes it to stutter when scrolling. Nod32 is trying to scan it on opening. So I end up waiting about 30secs or so for it to calm down and be usable. I asked many times, and also see in here that I am not the only one who suffers. My biggest gripe is the freezing downloads...So I have ended up ditching Nod32 for the free MS Essentials Software even though I have like 4 months left of my subscription. You have one very unhappy customer, are you willing to win me back?
