BSOD after Trojan Removal


Tag0

Recommended Posts

Today, I was hit by a rather vicious Security Essential 2010 trojan. It replicated and installed a large number of other unwanted malware, one specifically attempted (and to my knowledge successfully) created content in my system folder. Thankfully, Malwarebytes' Anti-Malware pulled through and removed its existance, and I saw it no more.

Unfortunately the anti-malware software also removed the one injected file in my systems folder, which gives rise on why I am posting for help today. When I have my computer on a period of time, I encounter a blue screen of death with the DRIVER_IRQL_NOT_LESS_OR_EQUAL_ERROR. After some google research, it indicates that this may be due to a corrupt driver of some sort, etc. When I look at the specific error, it indicates that the error dealt with a file called ujdqqvv.sys, the suspicious system file that was created by the trojan earlier.

The computer is currently running Windows XP SP3, and is currently running sfc /scannow in hope that Windows XP can fix itself. However, is there an alternate solutionwhere I can either remove this problem or perhaps bypass it?

Thanks.

Hi, and Welcome to Malwarebytes!

Please read the following so that you can begin the cleaning process:

As we don't deal with malware removal in the General Malwarebytes' Anti-Malware Forum, you need to start a topic in the Malware Removal forum so a qualified helper can help you fix any malware related problems/infections you may have.

  • Please read and follow the directions here, skipping any steps you are unable to complete. Then post a NEW topic here.
  • After posting your new post, make sure under options, you select Track this topic and choose Immediate Email Notification, so that you're alerted when someone has replied to your post.
  • One of the expert helpers there will give you one-on-one assistance when one becomes available.
  • Please refrain from making any further changes to your computer (Install/Uninstall programs, use special fix tools, delete files, edit the registry, etc...) unless advised by a malware removal helper. Doing so can result in system changes which may hinder the attempts by a helper to clean your machine.

NOTE: Please DO NOT post back to (bump) your topic within the first 48 hours.

Replying to your own posts changes the post count and helpers are looking for topics with zero replies. If you reply to your own post helpers may think that you're already being helped and thus overlook your post.

    • If there is no reply from any experts after 48 hours, you can reply to the topic, asking for help again.
      Or
    • You may send a Private Message to a Moderator asking for assistance.

Alternatively, as a paying customer, you can contact the help desk at support@malwarebytes.org or here.

Please be patient, someone will assist you as soon as it is possible.

PS: Please use the "ADDREPLY" t_reply.gif button instead of other ones when you start replying. :P
