Just (last week) updated to the 1.3 version, no probs so far. I'm not sure if it was available in earlier versions, but the 'stealth mode' works a treat. Picks up nasties as they try and plant themselves on your system and prompts you if anything tries to make a sneaky registry change.
The guy who invented this piece of kit missed out big time - he could have (and perhaps still could) made a fortune.
