Sometimes, when doing an on demand scan with NOD32, the system freezes up totally, requiring me to reboot. It does this regularly, especially after the computer's been running for a while.. After I cold restart, then NOD32 will finish a complete system scan. I have heard this is a problem others have had too... (I can't remember when or where). I think it's registry based. I used to use jv16 tools but just switched to RegSeeker. I have Win XP Home. I noticed that NOD32 is the only AV that does this to my computer. Is there anyone that can suggest how I can stop this? I got rid of ZAPRO, thinking this caused the freeze up soemhow (I replaced it with Kerio, and IE Clean), and the problem persist. When I try out a software product or delete a software product, I usually just reclone my computer to the state BEFORE that software installed.. Also, I have noticed, that it doesn't happen to a collegue of mine, who just purchased NOD32 yesterday, and she has Wiin XP Home too... However, when I installed other av software, just to try it out, their scanner didn't do this.. When I installed the beta (long gone now), the beta did that too.... I have it set up to scan all files, and deep heuristics everywhere. If anyone has any suggestions, I would appreciate them... If it is registry based, may I ask, what would ESET recommend for an all around registry cleaner... Thanks, Shooter..
