It's the only real time anti spyware program on my girlfriends vista computer and it's prevented anything from getting on there so far.Every time I scan with all the on demand scanners there's never anything there.So it must be doing it's job.
It can act as a useful `startup change` notifier, but I generally disable the daily-scanner and run it manually once in a while. The Software Explorer element is also surprisingly useful. Check "Changes made to your computer by software that is allowed to run" (click here), then run a scan if anything suspicious shows up.
chances are it works behind your av so it will find very little most av programs detect spyware, and most anti spyware programs detect virus and most other malware. as brundle says it watches for changes in system and like most microsoft programs runs fairly un noticed. i personaly dont bother with it as i think it's not needed. i have never found anything on my pc's but harmless cookies which as easily wiped away with ccleaner. following the advances of security programs developing and becoming more 'multi tasked' i think these days layered security seems to cause more conflicts and is less and less needed.
Waste of time.I deleted it a couple of years ago did nothing and found nothing.it was getting a very bad write up in those days.About 50% liked it and 50% didn't.To me a bad average.Maybe it has improved a bit since then.
