After last update of this FREE
http://www.free-av.com/found a prog titled TR/Spy.KStaff with an included srlh3.Osetup.exe that the anti-virus prog said was a WORM.
Now deleted.
Like this software. Finds stuff adaware, spybot search & destroy, spywareblaster, and spywareguard seems to miss.
May sound paranoid to some of you but have gotten some ugly spy stuff etc. in the past.
