Hi there. I appear to be infected with some Malware. Avast! is identifying krhwcot.sys as a possible Win32:Bubak rootkit. From what I can tell, its primary purpose is link redirecting in internet browsers. It also sent some spam messages via my Facebook account. It has also disabled the "Folder Options" when viewing folders and made hidden files invisible by default. Last but not least, I am having periodic blue screens with "IRQL Not Less Or Equal" errors. So far, these screens appear to briefly for me to see the specific error listed.

I have run Avast!, Malwarebytes Anti-Malware, SuperAntiSpyware, Spybot, and AdAware, but none are able to resolve the problem. At best, they are detecting krhwcot.sys as a probably rootkit and the following registry value hijacking:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer\nofolderoptions (Hijack.FolderOptions)

I'm running a Windows XP computer with Service Pack 3.

I'm assuming this is a new variation of some virus, so I am updating my anti-virus programs as often as possible (updating can trigger crashes too, depending on the program). Any help with this would be much appreciated, though.

Please follow the instructions in ==>This Guide<==. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then make a NEW TOPIC and post it ==>HERE<== Please include a description of your computer issues and what you have done to resolve them.

If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.
