Hi gurus,

My desktop is infected with trojans and viruses, and they have made it dead slow. Particularly, when i try to open yahoo mail or other messengers it doesn't loaded well and cabinet makes lot of noise too. Following are the trojans and viruses i noted:

1. Downloader.Tiny.R

2. Exloit (virus)

3. Downloader.Generic7.0RH

4. PSW.OnlineGames.2.S

Whenever my yahoo email loads, Microsoft Office Professional 2003 installation begins automatically and ask to insert the CD. Also, a Windows script host dialog screen pop-up showing that a script named Gameeeeeeeeee.vbs could not be run due to a runtime error. All these observations are very strange for me and i am not so much aware of them what they are.
Please help me clean my desktop by these attacks.

Regards
Vishy

Hi and welcome to Bleeping Computer!

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.

Hi vishy,

No you don't have to paste them.
I did see a few of these:

C:\WINDOWS\system32\amvo0.dll (Trojan.Agent) -> Delete on reboot.


Malwarebytes needs to reboot in order to remove this type of infection. Please reboot your computer after the run and then grab the log. :thumbsup: Please update and rerun Malwarebytes.

Then:
Lets see if anything is left out there.

Please download ATF Cleaner by Atribune & save it to your desktop.
