Hey :flowers:

I have recently been asked to help out a couple of my friends to clean up some troubles they are having with their computers. and while I talked the first guy into a system restore and he is happy about that, the other guy I think I will be able to save his machine.

So here is what he's got going on.

First off I was asked to help because he had antivirus 2008 which he paid for :thumbsup: which then lead him to upgrade to av2009 which he hasnt paid for.

the good news is he got the money back for 2008 but there was still the garbage on his computer.

so I happened to already know how to take care of av2009 based on some research deleting the registry entries and files from the computer. That was easy enough.

the bad part is there is alot of other stuff on there.

After killing av2009 and realizing his mccafree was dead I downloaded AVG free for him, which has an error with one file (asking to end task on a non-responsive avgsomthingerother.exe which I can find out the exact name if needed but dont know it off the top of my head) but then pulls up several infections.

here is a list of those files.

micro antivirus (microav.exe)
vrm2008.exe
__c00d356d.exe
winlogon.exe(616) (I guess they infected his winlogon file)
scui.cpl
explorer.exe(1824) (they got his explorer as well)
__a00f156701.exe
killav.exe
spy defender
_matrix.dll
c:\program files\pchealth\1.exe 2.exe 3.exe 4.exe and 2 different copies of 5.exe
system.exe (on the root of the c drive)
virusremover

and when shutting down windows it hangs on pwbkring.exe (but that might be legit)

so I started trying to tackle micro antivirus the same way that I did av2009 (or at least the part that I could guess) by going through the registry searching for micro antivirus and microav and deleting all keys and then deleting all files the same way...

the problem with that is one of the registry keys was hung up and wouldnt let me delete, as well as one of the exe's windows says that I cant delete them.

I tried booting into command prompt safe mode but it crashes when loading video drivers.

so I guess my main question is...

is there something bootable that I could run on this guys computer that would at least make it so that I can get in there and take care of this stuff with avg? I see that stinger by mcafee can do that kind of thing but I dont see microav on the list of stuff that it takes care of.

also, would disabling system restore help to make it possible to take care of these infections better?

anyway... sorry for this initial post being long, I just want to be thourogh and explain everything up front.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes.

yeppers ~PrEmIuM~, it managed to trick my buddy pretty good... that's for sure.

Thanks to you both, I will give Malwarebytes Anti-Malware a try when I go over there next.

does anyone have an approximate idea on how long it takes to run malwarebytes? the computer I am working on is pretty decent performance wise since even with all this junk on it I can still manage to use the machine. average size drive...

so what do ya think? about the same as a full antivirus scan with most applications?

I have seen scan times reported on this forum ranging from a few minutes to an hour, but mostly the former :thumbsup:

The speed of an anti-virus or anti-malware scan depends on a variety of factors.
  • The program itself and how its scanning engine is designed to scan - using a malware database vs heuristic scanning for suspicious behavior.
  • Type of scan performed: Deep, Quick or Custom scanning.
  • What action has to be performed when malware is detected.
  • A computer's hard drive size.
  • Disk used capacity (number of files to include temporary files) that have to be scanned.
  • Types of files (.exe, .dll, .sys, archives, etc) that are scanned.
  • Whether external drives are included in the scan.
  • Competition for and utilization of system resources by the scanner.
  • Other running processes and programs in the background.
  • Interference from malware.
  • Interference from the user.
