My work computer has been infected with a Trojan that cannot be cleaned.
We use Vipre anti virus and it has been finding Trojan.Win32.Generic!BT. When I choose to quarantine or remove the virus I get a message saying that the clean has failed. I also scan with Malwarebytes and it does not pull anything up.
As a result of this virus, my computer randomly restarts, my google searches redirect to other websites, and I cannot turn on my firewall. When I try to turn on the firewall I get an error code of 0x8007024.

I am at this computer Monday-Friday 8:00am-5:00 pm, so if my responses are delayed, this is why. I hope you all can help me out! Thanks!

I should also add that I have tried restoring my computer to an earlier time and the restore fails.

I hope these are better! I double checked that I had the settings right, but the one for the Mini Toolbox looks the same as before.

You have a system file rootkited.
That will require advanced help.

Please follow the instructions in ==>This Guide<== starting at Step 6. 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, what you have done to resolve them, and a link to this topic.

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.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
