The other night, an Antivirus 2010 "scan" popped up on our home computer (I'm currently on a work computer). I avoided clicking on it, and shut the computer down and rebooted in hopes to be able to run an immediate scan. Well that didn't work. Now when I turn it on, my desktop goes blue (all icons are still there), and I get a big black box that says your system is at risk and a separate dialog box that tells me that a scan needs to be run (with many misspelled words.) I obviously know this is not legit, but I still cannot get it to go away.

I had Malwarebytes installed, tried to run it, and it shut it down shortly after starting it. Trying to run it after that I get the message "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item". I was able to uninstall and reinstall it, and it repeated the same process over again. I tried renaming the mbam.exe file, but it wouldn't let me. I have received similar results from spybot as well.

I tried some scans from a flash drive that were downloaded from a clean computer, such as a-squared, clamwin, and superantispyware and got mixed results. Clamwin and A-squared both were able to complete scans and detected some trojans, and subsequently remove them. But when I run superantispyware, it detects "Trojan.Dropper/SVCHost-Fake", but shortly after detecting it, the program shuts down complete. I've tried pausing the scan shortly after detecting it, removing those files, then rebooting, and the file is still there.

I can run rkill over and over and over again, and it always tells me that it shut down \.\globalroot\device\svchose.exe\svchost.exe, but I can run it 30 seconds later, and it's there again.

I've tried running HijackThis (saw it as a recommendation on another forum), and it appears to run completely, but shuts down within seconds after a logfile shows up.

I feel that I've done all I can do with my limited knowledge/experience. Can anyone help me thru this?

Thanks very much.

Hello and welcome, this does appear to be a Rootkit infection. Let's not use HJT ,but DDS instead.
We need a deeper look. Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Let me know if that went well.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic355338.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.

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