I do not blindly trust such software anyway...
I need to look, find where the bad stuff is hiding, find out how i can safely remove it without fudging up the system, and then check that the Job has been done properly.
Blindly bombarding your windows with such stuff...
That is boring, and i do not learn a damn thing.
Not learning, is not progressing.
Not progressing is doing a bad job.
and as innovative and creative one is supposed to be as an IT support tech...
doing a bad job is not an option!
so i fully agree - careful with that stuff.
