Having the same problem with multiple customers computers, it started about last week. Combofix didn't even do a thing to resolve the issue. Reformating is not an option. Tried Mbam, ComboFix, AVG. Checked services settings (DHCP turns off after every reboot) but the other services remain okay, and checked every proccess running Disabled all startup items, checked hidden hardware, did SFC scans; nothing worked. HijackThis also renders no useful information. Originally thought it to be a OS related problem, but after we started seeing more computers come in with the exact problem, starting to lean towards it being a virus, or maybe a problem with a recent windows XP update. If anoyone else finds something out please let us know.

Thanks!

EDIT: Moved from XP to Am I Infected forum ~ Hamluis.

Hello,

Please follow the instructions in ==>This Guide<== starting at step 6.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Since you have run ComboFix, please include the ComboFix log in the new topic along with a description of your computer issues and what you have done to resolve them.

If you cannot produce any of the other logs, then please create the new topic anyway, include the information that you were unable to produce the other logs and why and include the ComboFix log along with a description of your computer issues.

No offense meant by this, but I know how to read diagnostics and logs; part of my job. Anyway, thank you for the assistance! I did finally solve this issue. This particular malware ended up being a rootkit that modifies different .sys files in the sys32/drivers folder. You'll need to use whatever tool, or manually check each driver file for modification, and replace it. In this case, atapi.sys (a common one), pciide.sys, rasacd.sys, and kbdclass.sys were all modified on different machines; the replacement of each of those solved the issue.

Thanks again guys! I hope this helps whoever else encounters this problem.
