Got hit by another one yesterday!
Security Tool got into my system  :-/ Perhaps my own fault. I had minimized my UAC settings in order to be able to edit the various .cfg files,and ommited to put it back up again in win7; It took all my .execs
and disabled them.
Luckily I managed to download other Removal tools and Spyware Doctor; And that did the trick and I'm operational again
