ya know, i like this program!! tried it after the avg merge and found it to be just as good. i read up on it and it seems to have a good detection rate too. (to me, detection rate is EVERYTHING, thats why i use avira antivir, but thats another topic). another plus, let it start with windows, it's in your task bar, and auto updates. the on demand scanner is lightning quick. did i say auto update? wow! lots of options, even in the free version. easy on resources. almost too good to be true. so far i am pleased with it. there is a pre release version out right now. http://www.superantispyware.com/?rid=3011
if you're bummed out about losing avg anti spyware, this may make you happy again.
edit: i said auto update...web site says no. sorry. really don't understand it, mine seems to update by itself.
