hey man, sounds like you just need to do some standard maintence. you said you already have ada-ware. I would suggest also getting spybot. between the two you get rid of pretty much all the spyware. but they do like to try and delete eachother. also a few other maintence things would be to run a disk cleanup(doesn't do much but doesn't hurt to try it) and then defrag your system. that will prolly take acoupel hours if you have a slow pc with alot of stuff on the hard drive. so just set it to defrag and go home at the end of the night.
as for the "system idle process's" they are part of windows, a buddy and I looked them up awhile back and it's windows using your free CPU time to defragment files in the back ground. so I wouldn't try to delete that. with those few simple things you should be back up to speed, maybe do em acouple times over the next week or so and you're computer will run nice again.
