Hi All,

I found that my computer was infected with various viruses and trojans that were identified by AVG Anti Virus. AVG was unable to remove these infections so after some searching I discovered this site and downloaded Malwarebytes Anti-Malware.

The Malwarebytes Anti-Malware software has identified 6 infections but also does not seem to be able to permanently remove these infections.

The steps I have taken before running Malwarebytes Anti-Malware are:

1/ Turn off system restore in Windows XP

2/ Start XP in 'safe mode'

3/ Run Malwarebytes Anti-Malware in 'safe mode'

4/ The software seems to identify infections relating to Winqx64 and WinCrtl32.dll

This is the log file created by Malwarebytes Anti-Malware after running the scan:

Malwarebytes' Anti-Malware 1.29
Database version: 1305
Windows 5.1.2600 Service Pack 2

Files Infected:

The log says these infections will be removed after reboot but not working.

Your help would be massively appreciated!!!

Please help!!!

Thanks :thumbsup:

I'm pretty sure MBAM is supposed to be run in normal mode to remove infections. You should do the scan again in normal and see if you can remove the problem. ;)

maybe try this ?

Please update the program then run in Normal mode

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.
Please then copy and paste the contents of that report for examination 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, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

I note you have turned System Restore off? It is normally recommended to leave System Restore turned ON as it is better to have an infected Restore point available if things go 'pear- shaped' during clean up than none at all :thumbsup:
