Hi all,

I find myself in the unenviable position of having to try and fix a colleagues PC. We are a very small company, and the colleague in question is the Accountant so this is kinda serious. Today I established that SpyHunter and Avast! while they appeared to remove everything (and included a scan before boot), as soon as we reconnected to the internet the whole spoof virus thing started over. Its been a while since I needed to use HJT so I am the process of re-learning the procedure. Thats for tomorrow, for now I wanted to pass on a few of the symptoms because I wonder if they are typical of MSAS2009:

1. I could not perform system restore (always my first port of call).
2. I beleive that Windows firewall had been turned off by MSAS2009.
3. I could not use the Explorer option Tools>Folder Options, the menu item has disappeared, meaning of course that I can't easily see any of the system files.
4. Avast! had been disabled - I had to download and install the latest version via a flash drive.
5. From time to time Windows would display the message that it was going to shutdown because something had requested something to close, and this would occur in 45 seconds.. (I don't recall the exact dialog but I have seen it before occasionally if you Kill certain processes)

My impression was that MSAS2009 was nuisance rather than a damaging virus - but if the above symptoms are real maybe we have more than MSAS2009 on out hands?

Any ideas are more than welcome.

Hi,

Please do this:

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 Download_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 and you may be prompted to restart your computer. (see Note below)
  • 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 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. Failure to reboot will prevent MBAM from removing all the malware.

Hi,

Please use the Internet Explorer browser (or FireFox with IETab), and do an online scan with Kaspersky Online Scanner

Note: If you have used this particular scanner before, you MAY HAVE TO UNINSTALL the program through Add/Remove Programs before downloading the new ActiveX component

Click Yes, when prompted to install its ActiveX component.
(Note.. for Internet Explorer 7 users: If at any time you have trouble with the "Accept" button of the license, click on the "Zoom" tool located at the bottom right of the IE window and set the zoom to 75 %. Once the license has been accepted, reset to 100%.)
The program launches and downloads the latest definition files.
  • Once the files are downloaded click on Next
  • Click on Scan Settings and configure as follows:
    • Scan using the following Anti-Virus database:
      • Extended
    • Scan Options:Scan Archives
      Scan Mail Bases
  • Click OK and, under select a target to scan, select My Computer
When the scan is done, in the Scan is completed window (below), any infection is displayed.
There is no option to clean/disinfect, however, we need to analyze the information on the report.

To obtain the report:
Click on: Save Report As (above - red blinking arrow)
Next, in the Save as prompt, Save in area, select: Desktop
In the File name area, use KScan, or something similar
In Save as type, click the drop arrow and select: Text file [*.txt]
Then, click: Save
Please post the Kaspersky Online Scanner Report in your reply.

Hmm, back to square one, it took about 30mins to download all the Kasparsky updates, during which time the whole thing fell apart again - never got around to running it. Multiple viruses - all kinds of problems, however I did manage to get the latest updates for mbam so I am disconnected from the 'net again and re-running that mbam - watch this space.

Well as usual things got a lot worse before they got better - I had to leave the system in a usable state (even if it was not connected to the internet) so here's what I did:

Ran a full scan with the updated version of mbam - twice and it did find some extra problems - which I removed. I then ran a full scan with Avast! and also with Spyhunter.

All through this process I had been plagued by a stalled installation of one of the apps on the PC - it kept trying to re-install itself right at boot time which made life even more difficult so I spent some hours trying to figure that out...

Also the system kept shutting down with the "Win32 process error..." problem. I decided to take a chance on the virus and re-install XP SP#3 but I had to do an upgrade (we could not afford to do a full installation not knowing what was backed up).

After that everything seemed OK - I ran all the various tools again and they showed no problem, the system is performing well right now - I have left strict instruction NOT to connect to the internet until I get back...

Just before leaving I ran Hijack this and I will post the log over on the HiJack this forum.

Hopefully things are OK but we won't know for sure until I have them re-connect to the internet.

Thanks for all your help!

Geoff

Hi,

As you have posted a Hijackthislog, I may not help you anymore, because I'm not a Hijackthis Teammember.
Please wait, untill a HJT teammember will answer your log.

I will inform a moderator to close this topic. :thumbsup:
Good luck
