Trojan infection creating BITxxx.tmp files constantly

Unread postby ThePalad » October 23rd, 2007, 8:28 pm

Thanks to some dodgey activex control, my computer is infected with some form of trojan horse. It keeps creating BITxxx.tmp files in my temp folder, you delete them, they keep coming back with a different "xxx" and the last one created cannot be deleted when on the internet because it is "in use by another person/program". Avast antivirus noticed it but obviously didn't stop it. I tried SDFix followed by Combofix which seemed to get rid of it, but the BITxxx.tmp files are still appearing at about 370KB each. Running ActivePorts I find that the BITxxx.tmp files are appearing everytime svchost.exe accesses or is accessed by svchost.exe by the IP address 81.29.248.50 (and no, this isn't my IP address). I'd be very grateful if anyone could help me remove this annoying trojan....hijackthis report is included.

Oh and I forgot to mention, the start menu is totally messed up too, looks kind of like a windows 95 start menu, and I imagine it's related....

Hello and welcome to the forums

My name is Katana and I will be helping you to remove any infection(s) that you may have.

Please observe these rules while we work:
1. If you don't know, stop and ask! Don't keep going on.
2. Please reply to this thread. Do not start a new topic.
3. Please continue to respond until I give you the "All Clear"
(Just because you can't see a problem doesn't mean it isn't there)

If you can do those three things, everything should go smoothly :D

There is nothing dramatic showing in your HJT log :)
Do you have the ComboFix log ? ( C:\combofix.txt)
