I recently got ESET Smart Security to replace my previous one, which was rather slow and expired anyhow and I've read that ESET tends to have rather fast scan times. I have Windows 7 Home Premium edition if that means anything. I try and initiate a smart scan and it seems to hiccup rather often. Like, it's doing it thing then it freezes up, and freezes any other program I was using up, but continues on its way for a little bit. At 59%, 44716 scanned objects in, it freezes up almost completely. I'm unable to use any program I was using at the time until I can get the scan cancelled, which takes a while to initiate, and even longer to finally go through so things go back to normal. Right now, I'd be happy just to be able to complete an entire scan without everything freezing over, regardless if it takes six hours to complete.
