WIN32 Krepper.C and J2

Hello. There appears to be something funny with my computer. Avast is able to detect them and then I will delete those files. The problem is that they will reappear again, this time as different file names. And then worse, they will be detected again but then when i try to delete or move those files into chest, Avast says that they could not find the file specified. Usually, this is the file that it discovers…

C:\Windows\System32\w8c6s4xcm66s.dll

The when I delete it, it would say that C:\Windows\System32\w8c6s4xcm66s.dll is infected with WIN32-Krepper.C [trj] and then Win32-Krepper.J2 [trj] a few minutes later. Coud anyone here please help me out?

Here is the log of my hijackthis…

Which files should I clean and delete?

Hi, r2ro.
Your online report (it will be there for 3 days): http://hijackthis.de/logfiles/4093ff0a893d6642dda7ff961f5b0d3b.html.

Also, you should secure your system more. Take a look at my website for some free security tools.
