My computer has the dreaded sirefef! I'm running Windows Vista Home Basic Service Pack 2. 32 bit.

A few weeks ago Microsoft security essentials (mse) stopped running. I tried to start it again but a message came up stating that the program didn't exist as an installed service. I also noticed that windows defender was off and it also claims it doesn't exist as an installed service (error 0x80070424). When I tried to reinstall windows defender, it popped up a message "Windows Defender does not need to be installed because it is included with windows vista. You can access it from the control panel."

The other day I decided to try to get Security Essentials running again by uninstalling it and reinstalling it. It worked and began to scan my computer. It found two threats: sirefef.AH and sirefef.R . I clicked clean threats and mse started cleaning them. HOWEVER, sometime after I got mse running again, I got a notice that read: "Windows has encountered a critical error and will automatically restart in one minute. Please save you work now." My computer restarted and I got that notice again. I tried safe mode and I still got that message and force restart, but it happened slower. In I ran mse again, it saw the same threats, I clicked clean, and It claimed they were cleaned (I know they aren't because my computer would still get that message). Eventually I chose the option "Repair Computer" from the F8 menu and went to a restore point 2 weeks earlier. (But not without stupid messages claiming "the restore wizard is already running. This program will now exit." After a few minutes the wizard would pop up just fine.)

So now I'm at a restore point before I reinstalled mse (so mse and defender are not working). If I try to install and run mse again, it just starts the whole process again and I have to do another restore point. I ran Malwarebytes and it didn't find anything. I also ran RougeKiller and deleted files that it found malicious. (ones with names like U,c,@) I also ran ComboFix. Then I tried to Windows Fix It which did nothing. Nothing is killing this virus. I would like to avoid reinstalling my OS but I will if I have to.

Please help. Thanks in advance.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic464893.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

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

To avoid confusion, I am closing this topic. Good luck with your log.
