I've installed and tried 2.5, and I tried 2.12 last year (and I did buy it), but I keep having trouble pulling the trigger and completely making the switch (from McAfee). Some of it's just that I'm used to McAfee, some of it's because I read stuff on these forums about missed trojans or missed virii. Last year it was because IMON was having to be set into higher compatibility mode all the time in order to keep problems from occurring on various websites. On the other hand, I also run BOClean and TDS-3 so missed trojans shouldn't worry me ... So, let me get the scoop from you who have been using NOD32 for some time. To me, 2.5 is far more polished than 2.12 was and I'm really tempted to just drop McAfee ... but it's still hard for me to pull the trigger. What do all you long-term users think? Have any of you: a) had problems you just couldn't get around with NOD32? b) had serious issues because NOD32 missed a virus that say, Norton or McAfee would have found? etc. etc.
