Hello,

My Dell desktop computer has apparently been badly infected and I am not sure how to proceed. I cannot, even in Safe Mode, open any programs--including Firefox and Internet Explorer. Therefore, I cannot download any antivirus removals or anything.

When I try to open any program, a DOS window pops up for about half a second, which I think reads something along the lines of "There is not enough memory to run this program", but it is so fast I can't be sure. The desktop icons also look different, in that they all have a black "shadow" behind them now. I was able to open file folders and look at Windows Explorer so I don't think it is a hard drive issue, per say.

Also, we have run Spybot Search and Destroy (obviously before we were unable to run any programs) and it apparently didn't catch whatever has taken over. We have noticed a difference in the computer's performance lately (running more slowly), but it didn't completely become useless until this morning.

Is there anything I can do, short of wiping the computer clean and starting anew? I have already backed up all of my files, just in case that is my only option.

Any help would be greatly appreciated!

Thanks so much!

Hi,

Well, as I look to your story, I think the best option is to reformat the system.
It's heavily infected. Even if we clean it, we can't be sure it will ever be normal again.

I hope I answered your question this way. :thumbsup:

I appreciate your help. I actually found out that the problem stemmed from desot.exe (I think that was the name). I found out how to delete this and it seems to be running normally again. I am sure it is a temporary fix, as this is bound to happen again, but we will see.

Thanks again for your input--if it happens again, you better believe I will be doing what you advised!

Hi,

Well, if it's normal again, we can maybe look something deeper? :thumbsup:
Only if you want. Do this then:

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

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.
  • 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Thanks Superbird.

Unfortunately, I can't access any of those links to download. Do you have any other suggestions? Now, the computer programs are working fine, but the internet has gone out of whack. It redirects some of my searches or doesn't allow me to access sites. I believe that this particular time stems from a hack to my Facebook account, if that helps. I am getting pop ups randomly that don't show anything on their screen.

I am getting rather frustrated!

I appreciate your help so far!!!

Here's one more link for you to try.
http://www.filehippo.com/download_malwareb...i_malware/tech/

If that doesn't work, do you have access to another PC? If so, you can download the Malwarebytes installer to a flash drive and move it to the infected machine.

Back to you superbird :thumbsup:

Actually, I can see already that it didn't fix everything. I am hoping there is more that can be done.

Thanks!!!

Hi,

Please do a new, full scan, with MBAM and delete everything that has been found. Post the logfile in your next reply. :thumbsup:

Also do this, AFTER the MBAM scan and a REBOOT.

Please go to Kaspersky website and perform an online antivirus scan.
  • Read through the requirements and privacy statement and click on Accept button.
  • It will start downloading and installing the scanner and virus definitions. You will be prompted to install an application from Kaspersky. Click Run.
  • When the downloads have finished, click on Settings.
  • Make sure these boxes are checked (ticked). If they are not, please tick them and click on the Save button:
    • Spyware, Adware, Dialers, and other potentially dangerous programs
      Archives
  • Click on My Computer under Scan.
  • Once the scan is complete, it will display the results. Click on View Scan Report.
  • You will see a list of infected items there. Click on Save Report As....
  • Save this report to a convenient place. Change the Files of type to Text file (.txt) before clicking on the Save button.
  • Please post this log in your next reply.
If you need a tutorial, see here

Ok, I ran a Full Scan again and got this mbam-log:

Malwarebytes' Anti-Malware 1.40
Database version: 2551
Windows 5.1.2600 Service Pack 3

9/1/2009 3:38:15 PM

Files Infected: 0

Memory Processes Infected:

I then rebooted and proceeded to go to kaspersky.com (through your link and also on my own) and was not able to access this site. Something is still blocking my access to certain sites.

Any ideas?
