msconfig and more

[oo7sk8punk]

well ive recently been infected by a trojan and a worm (i know i need to beef up security) for the most part have removed them with the help of other fourms but i thought id pose my new questions at some windows "experts" for starters one day i decided i didnt need 42 processes runing so i read up on things and tried to run msconfig and i seen nothing, it shows up in my taskmgr, as using 99-100% of cpu, but nothing on screen...also in an effort to clean up my clutterd HD i went searching for extremly large files and found 2 (in my opinion) very questionable windows files system.ini and win.ini both of which are 3.99 gigs, now of course i could be wrong but isnt that a bit much for a .ini, any hiya and thanks to anyone who can lend a hand, need any more info to assist ya with fixing this and ill see what i can do

edit: fyi i since got a third party program to streamline my startup and down to 33 processes
