Hello,

I'm having a problem with a nasty malware virus and I don't know what to do about it. I am running Windows XP on an old Dell laptop.

I've been running AVG's free anti-virus software for the last few months and it recently has started picking up something it identifies as Win32/Cryptor. AVG can't seem to fix the problem, so I went to Trend Micro's House Call. I've run about five of those now in the last two days, and it keeps coming up clean.

Meanwhile, I downloaded LavaSoft's Ad-Aware, and I keep getting a message balloon, immediately at start up and every few minutes afterward:

Ad Watch Live! detected that malicious process is running and started scan in background mode. You will be able to clean infection safely after scan has finished.

Once Ad-Aware finished scanning, it shows me the results and I do the recommended action to fix the problem, which it identifies as Win32 Trojan Olimark. Immediately after this, the balloon appears again, and the process starts all over. When it restarts, it will shut down something else that I have open, like AVG or a Firefox window.

I see that other people have had a similar problem, but the explanations of how to fix the problem are very confusing and may not apply to my exact problem. I need someone very patient to help me through this; I'm not a computer expert by any stretch of the imagination. Thank you!

Hello.

Please run MBAM first. After that post back with the AVG log so I can see what it's detecting exactly.

Download and run MalwareBytes Anti-Malware

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.

For complete or visual instructions on installing and running Malwarebytes Anti-Malware please read this link

With Regards,

Hi,

Thanks for taking the time to respond to my post. Sorry that it took so long to respond; between commuting, work and school, I barely have time to sleep let alone turn on the computer.

I downloaded the program that you recommended but, this is going to sound stupid, I can't get the program to run. I double clicked on it in my download window and it wouldn't run, and then I double clicked on it on my desktop, where I downloaded it to, and it wouldn't work from there either.

Every time I try to run it, I get that message from Ad-Aware saying 'malicious process is running and started scan in the background..." etc.

Thanks for your time!

Hello.

Seems there's a rootkit or something involved here. I can't be exactly sure however.

See if you can run GMER.

Download and Run Scan with GMER

We will use GMER to scan for rootkits.
  • Double-click on Gmer.exe to start the program.
  • Allow the gmer.sys driver to load if asked.
    If it detects rootkit activity, you will receive a prompt to run a full scan. Click Yes..
  • When it's done scanning, you may receive another notice. Click OK if prompted.
  • Click on Save ... to save the log on your desktop.
    Save the log as GMER.txt when you save it on your desktop.
  • Close Gmer and copy and paste the contents of GMER.txt in your next reply.
  • If you receive no notice, click on the Scan button near the bottom.
  • It will start scanning again like before.
  • When it is done, Click on Save ... to save the log on your desktop.
    Save the log as GMER.txt when you save it on your desktop.
  • Close Gmer and copy and paste the contents of GMER.txt in your next reply.If GMER doesn't work in Normal Mode try running it in Safe Mode
Note: Do Not run any program while GMER is running

Important!:Please do not select the Show all checkbox during the scan.
