I actually uninstalled this. One thing I liked about the previous version was I could have it installed, run a scan with it, then completely shut it down. This new version however, is much more recalcitrant. Even setting it to not run all the time, to not run on startup, and removing the startup entry, it still loads something at startup and keeps it there. If you open it, scan and then close it it leaves at least 2, if not 3 processes running that have to be killed from Task Manager. I didn't look to see if it also has an associated service with it.
Seriously, if I can't control a program, I won't run it. I think it sucks that it leaves processes loaded and running even after you close the program. And forcing me to have something run on startup is just crap. I surf safely, and have never had spyware problems. Not too worried about not adding this to my already considerable line of security.
