Hi everyone,

This is the first time I've ever been really stumped by a virus problem, so it's my first post here -- but thanks to all those whose previous posts helped me out of quite a few problems.

I'm running Windows XP Version 2002 with Service Pack 2 on a Dell Latitude D600 laptop.

I started to suspect something was wrong when I tried to open Malwarebytes Anti-Malware for a routine check, but couldn't. So here's the summary of my symptoms:

Can't run MBAM, HijackThis, Symantec Antivirus, Spybot Search & Destroy, SuperAntiSpyware, or Ad-Aware. Can't run Windows Update. With MBAM and HJT, I can rename a copy the executable and it'll open, but it shuts down if I try to run a scan; and if I try to open, move, or rename that copy of the program subsequently, the operation will fail with the error, "Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the file."

However, Process Explorer works, and shows the process "UACweetmlodnkppmng.dll" running from "\\?\globalroot\systemroot\system32\UACweetmlodnkppmng.dll".

I hope one of you can offer some advice about what to do next, or what additional information would be helpful! Thanks a lot --

Hello and welcome to Bleeping Computer.

Please subscribe to your topic so that you will be notified as soon as I post a reply, instead of you having to check the topic all of the time. This will allow you to get an email notification when I reply.

Ok, next, let's run RootRepeal, it looks like you have a rootkit.

Please install RootRepeal

Go HERE, and download RootRepeal.zip to your Desktop.
Tutorial with images ,if needed >> L@@K
Unzip that to your Desktop and then click RootRepeal.exe to open the scanner.

*Open the folder and double-click on RootRepeal.exe to launch it. If using Vista, right-click and Run as Administrator...
* Click on the FILES tab, then click the Scan button.
* In the Select Drives, dialog Please select drives to scan: select all drives showing, then click OK.
* When the scan has completed, a list of files will be generated in the RootRepeal window.
* Click on the Save Report button and save it as rootrepeal.txt to your desktop or the same location where you ran the tool from.
* Open rootrepeal.txt in Notepad and copy/paste its contents in your next reply.
* Exit RootRepeal and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

Please note: If Rootrepeal fails to run, try this step: Click Settings - Options. Set the Disk Access slider to High


Note 2: If RootRepeal cannot complete a scan and results in a crash report, try repeating the scan in "Safe Mode".

Computer Pro--

Thanks. I'm in safe mode, but RootRepeal scans for about five seconds, then closes, and the executable becomes unresponsive when double-clicked. If I re-extract the file, I can run it again, but I get the same result.

Try to run it in normal Mode, otherwise, try to rename the file to ZZToy.exe before you try to run it

Well, that was instructive! I'm now totally reminded of why I had this computer set to boot automatically in safe mode (I haven't had to use it in a couple of months, but recently had to give up the other computer I'd been using).

Specifically, in normal mode a ton of fake "virus warning" messages pop up, trying to get me to install "AV Care" and "PC_Antispyware2010," which now show up on my Start menu under All Programs. I also saw "b.exe" operating on Task Manager, which I know is often associated with virus activity. I wish I had remembered all this earlier to tell you.

And, unfortunately, your last suggestion didn't work. Even if I rename RootRepeal to ZZToy.exe, if shuts down automatically -- after ten seconds or so in safe mode, a minute or so in normal mode (probably because things are so much slower with all the virus crap trying to run). It shuts down while attempting to scan the directory "C:\WINDOWS\$hf_mig$\".

Also, when I shut the computer down to restart it, a standard Windows notice appears to tell me that the program "Sample" couldn't be shut down automatically.

Any next thoughts? I'm back in safe mode, of course. Thanks for your help so far.

Please download Dr. Web the free version & save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr. Web Cureit as follows:
Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
The Express scan will automatically begin.
(This is a short scan of files currently running in memory, boot sectors, and targeted folders).
If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
When complete, click Select All, then choose Cure > Move incurable.
(This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
Now put a check next to Complete scan to scan all local disks and removable media.
In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
In the top menu, click file and choose save report list.
Save the DrWeb.csv report to your desktop.
Exit Dr.Web Cureit when done.
Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

Well, here's what happened:

I initially ran Dr. Web from my current mode, which is Safe Mode With Networking. The Express scan ran as intended, and found four items which it successfully deleted. Then I ran the Complete scan. Maybe three or four minutes in, the program spontaneously closed. It doesn't appear to have produced a logfile, and unfortunately I didn't write down the names of the items found on the Express scan. Further attempts to run Dr. Web resulted in an almost immediate termination on running the Express.

So I decided to reboot in Safe Mode without networking. On restarting, I received a new window titled RUNDLL reporting, "Error loading tapi.nfo. The specified module could not be found." I think "tapi" was one of the four items the scan had found.

At this point, I could run Dr. Web again. The Express scan found and deleted one item, called "c:\windows\system32\driverhjgruitttmpniq.sys", described as "infected with BackDoor.Tdss.266." The Complete scan, again, ran for about two minutes and then spontaneously closed. After this, again, it would crash even on the Express scan.

I rebooted again in Safe Mode With Networking to post this, and ran Dr. Web again first. The express scan found nothing; the Complete scan shut down as before.

Sorry, the entry in the previous post should have read:

"c:\windows\system32\drivers\hjgruitttmpniq.sys"

One more thing. I just tried to run RootRepeal (renamed as ZZToy) again, but it now gives the following error: "Could not read the boot sector. Try adjusting the Disk Access Level in the Options dialog." The error persists when I change the access level to High.

boopme,

Yes, RootRepeal will run on Low disk access, but it again closes automatically after a few seconds.

I can now open MBAM if I copy the executable to a new name. Unfortunately, my definitions are from April 25, and if I attempt to update the program will download the updates and close, but the updates will not show up when I reopen MBAM. Anyway, when I attempt to run a scan, the program closes and then cannot be reopened.

I will try killing UACweet..., but first a question. When I highlight it and click the X, Process Explorer asks if I'm sure I want to kill svchost.exe, the process UACweet is running under (there are five svchost's running). I did this once before (before posting on this forum), and the result was a failure requiring a system restart. I'll try it again if you want, or is there some other way of killing UACweet without killing svchost.exe?
