While running Zone Alarm Extreme Security my computer somehow became infected with backdoor.win32.zaccess.ob. I cannot find much info on this specific virus online. Four antivirus programs find the virus but cannot delete it. They all say they will delete on reboot or to reboot to complete the removal but my computer won't reboot. It appears to be shutting down, the screen goes black but the computer is still running. I have to turn it off manually by holding the button. This also happens even when I click to turn off the computer ever since it became infected. I have to cut the power manually.

Zone Alarm finds the virus as: backdoor.win32.zaccess.ob

Malwarebytes finds it as: TrojanDropper:Win32/sirefef.B.exe

SuperAntispyware finds it as: Heuristic Agent-stream/Resident

Searchbot finds it as the exe program that appears in my task manager.

I tried running in safe mode with networking but the virus is also active in safe mode! The only difference is that in safe mode the program does not appear in my task manager.

I have tried everything I know. I cannot kill it in task manager , it won't let any of my antivirus programs reboot to complete the removal. I removed what registry entries I could find but that didn't help.

This virus is attempting to broadcast my information to numerous IP's. Zone Alarm firewall is blocking the attempts, or it is blocking 257 attempts about every 15 minutes. I hope that is all of them.

How can I get this out of my computer when my computer will not reboot to complete the removal?

Any help will be very much appreciated.

Actually, you didn't post this in the wrong forum. I see that you have posted this anew in the log forum. I need you to do the following:

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

Once the proper logs are created, post them in a REPLY to your NEW topic here: http://www.bleepingcomputer.com/forums/topic423955.html

If you can produce at least some of the logs, then please post the reply 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 a reply 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.

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