no, actually this is the correct place to post that kind of stuff, tho it works on the general as well.
anyway, rouge programs or not, those stuffs shouldn't even be messing around the system, since Win7 pretty much sorts itself out really well.
Edit: oh yea, if it is a trojan or whatever, its pretty hard to clean those up, a reformat would be the best case. plus reformatting is the best optimization there is =P its similar to buying a new car i suppose.
