Hello,

I’m new to this site so I apologize if I’m not following procedure. I read up before posting but just incase I missed something, thank you in advanced.

I am using a work computer and it is shared by my self and two other employees’. One of them decided to watch a basketball game online on a site that has a million links and the following day when i came in, the computer was almost unusable. I hit alt+ctrl+dlt and i noticed that SVCHOST was running at 500k+ memory. I closed down the process and everything worked fine for a while. Then it started slowing down once again and the same process was running at high memory consumption. The same has been happening and i find my self force closing it every few minutes. I've fixed viruses on my own before but this one is kicking my ass. I ran malware bytes and nothing came back. I have combofix but I don’t feel comfortable running it on a machine that does not belong to me without proper guidance. I need help because the IT bill would come out of my check and i just can’t afford it. Any and all help is greatly appreciated, Thank You.

I’m Running Windows XP professional.

EXACTLY the same thing happened to me. I posted a thread here yesterday - http://www.bleepingcomputer.com/forums/topic449010.html.

It didn't affect my machine as badly, at least not at first, but then worsened. I am also running XP. Try the steps I did in the link above and I bet it works, mine is working fine now.

PS- Don't bother running the Microsoft program I ran, it's slow and wont help anyway. I would go right to the TDSS.exe on the kaspersky site, solved it almost instantly - http://support.kaspersky.com/faq/?qid=208283363
