Hi ive been infected with the trojan vundo, about a week ago i started noticing my computer was slower and i got some pop up adds ocasionaly so i suspected i had a virus so ive been constantly scanning with norton 360 but nothing came up until today. It detected the Vundo trojan. I asked norton to fix it but I guees it didnt since I kept getting infection alerts.
I downloaded Malwarebytes and ran a scan it detected some infected files and fixed them, it didnt ask to reboot but i did anyways. I ran another scan with malwarebytes and still get infection detected. I need help to remove this virus pls.
Im running windows XP
thanks in advance

It seems Malwarebytes did the job.
The first time i scanned it detected and fixed some files. After reboot it still detected some files but i noticed all the files detected the second time were on some sort of a backup restore folder here is the log.

Malwarebytes fixed this also.
After this I followed the procedure you told me too, downloaded both programs and installed and updated superantispyware, rebooted in safe mode did the ATF cleaner and then the full scan with Superantispyware this didnt detected any infections when finished. So I just closed it and rebooted to normal windows. It seems Superantispyware didnt generate a log since its not apearing my only guess is that it doesnt bc i signed in as administrator when on safe mode which is not available in regular mode.
Will watch for the next hours and report back with results.
Do i have to worry if I have other computers on the same network as teh infected one? I have a laptop with windows vista in the same network. Im also worried some info might be compromised since I did some payments online through pypal on t he infected computer through the week do I have something to worry about?

My understanding is that Vundo does not steal passwords, so you're probably okay there. Although, I would change the paypal password anyway and keep a close watch for any suspicious activity.

If you're worried about your other computer(s) run the Malwarebytes scan on them.
