Hello to the group! I've been a sand-bagger for 2-3 years now. I do Tech support, and usually I can do anything...but; not this time. I think this issue is worth sharing and working on:

My client's PC is infected with "Security Tool". That would not be an issue except the NONE of the tools recommended anywhere will take control of the PC. To be specific:
The OS is Vista Home Premium.
All tools are tried w/ "run as Administrator". All these tools are tried, but the malware kills them all.

No variant of RKill works, TFC does not work, Task Manager fails, McAfee can't be accessed, Safe Mode will not start (Yea, like...Wow...it won't start in safe mode! It just re-boots instead of progressing to the login)..

This poor person just bought this Laptop, so there's no user content to be concerned with. She needs to get back to College; so It's "Wipe and rebuild" for this one.
Still, we've got to find a way to take control when this malware is running!

So, your thoughts and time are appreciated.
What else could have been done here?

Try This:



Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to abcdefg.exe instead of mbam-setup.exe

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

Double Click abcdefg.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

Hi!
Ok; good point.
MBAM did install, and as per postings about this malware, the Core File was missing in the destination folder. I manually copied over this file.
MBAM would not launch sucessfully; the process appeared to be killed by the malware.
Renaming the executable is worth a try...

Anyone out there have an infected PC they can test this with?

Meantime, I will post this as a Query to the MBAM author, and see what he has to say.

Run this application before running Mbam


Please download Rkill by Grinler and save it to your desktop.Link 2
Link 3
Link 4
  • Double-click on the Rkill desktop icon to run the tool.
  • If using Vista, right-click on it and Run As Administrator.
  • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
  • If the tool does not run from any of the links provided, please let me know.
Do not reboot the computer or you will have to run it again

Garmanma and Mov Cx Ax, Thanks for the thoughts.
I tried to be clear in my first post:
No variation of RKILL worked. I tried them all.
I did not try renaming MBAM.EXE to .com. I can't test that now, as the client chose to re-load the OS and get back to school.
I did contact Malwarebytes.org......they feel that the rename trick, either changing MBAM.exe to 1234.exe, or MBAM.exe to MBAM.com might or might not work; it would be worth a try.

I'm going to keep working on this. Are there any other tools we might use?
