i am running win XP. when i first got on internet with my new puter i went and downloaded Kazaa.worked good 4 a day or two ,then funny stuff started to happen.I would notice my puter starting to slow down, then I started to recieve an uncontrolable amount of popups. Went and got Spydoctor,spybot,and ad-ware sptware removers.they all said they cleaned all up. But when i'd run the next program it would find the same files that the previos prgram had said it removed. I went through all 4 times with the same results. (DSO EXPLOIT). i removed Kazaa, still same. so I took drastic measure and reformated harddrive and started from scratch.after a day or two sqame thing again. so i reformated again. then just for curiusity i performed a seach for kazza on my hard drive (before internet connection) and i found a directory for kazaa, nothing in it but it was there. then i noticed this one time i had left my puter on downloading for a couple of hours that on my return my recieved info was in the range of 7,000,000 but my sent info was 15,000,000.when i left sent eas at 250,000. ihave norton anti-virus and formentioned free use spyware tools i mentioned. if anyone has any suggestions can u please email me at [email protected]. i did not install outlook express this time around to see if all that outgoing is from there.
