Hi to all,

This is re-post originally posted less than 10 minutes ago on " Windows XP Home and Professional" forum.

Problem
Selected friends on my MSN messenger list report a series of offensive messages from my MSN to theirs (links to restricted sites, p*rn sites/links etc). More than 5 friends reported this occurance, a series of message giving links/offensive messages (some posted what appeared on their msn window on mine but I deleted it).

What I did
I installed AVG and Zone Alarm (at the same time in the hope it would remove the virus/malware etc), my friends still report the same issues. I am told its not a good idea to install two Anti-Virus. I believe Zone Alarm is running the firewall and AVG is running anti-virus. Both are paid versions/not trial. If possible, is one better than the other?

Questions
MSN is installed on two PCs, my desktop and laptop, will I need to perform similar checks on both PCs ? I have the HJT log incase any would like to view it.

Appreciate all help and support offered. Thank you.

Please do not start new threads or duplicate topics as this causes confusion and makes it more difficult to get the help you need to resolve your issues. I will close your other topic.

Please download MsnCleaner.zip by ElPiedra and save to you Desktop. (in addition to removing infected files, it will remove certain restrictions on your system often disabled by malware.)
  • Extract (unzip) the file to your desktop. (click here if you're not sure how to do this) but DO NOT use it yet.
  • Reboot your computer in "Safe Mode" using the F8. To do this restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A boot menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".
  • Double-click MsnCleaner.exe to run the tool.
  • Click the "Analyze" button.
  • If an infection is found, click the "Deleted" button.
  • A report with the results will be created automatically after the scan and will be saved to C:\MsnCleaner.txt.
  • Reboot normally and post the contents of MsnCleaner.txt in your next reply.
Please download Malwarebytes Anti-Malware (v1.36) and save it to your desktop.

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.

Your Malwarebytes Anti-Malware log indicates some files will be deleted on reboot. If MBAM encounters a file that is difficult to remove, you need to restart the computer so the malware can be fully removed. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. If you have not rebooted, make sure you do this. When done, rescan again with MBAM (Quick Scan) in normal mode and check all items found for removal. Don't forgot to check for database definition updates through the program's interface (preferable method) before scanning. Then click the Logs tab and copy/paste the contents of the new report in your next reply. If you did reboot, then rescan again anyway and post a new log.

This is the most recent log. Is there any way to know if the issue with my msn sending messages is gone (asking people on my contact list if they are recieving messages?).

From the logs you posted, it doesn't look like we find much. Spambots, Botnets and Email relays typically come packaged with rootkits so a rootkit check should be performed. I recommend performing an anti-rootkit (ARK) scan with one of the following:Before performing an ARK scan it is recommended to do the following to ensure more accurate results and avoid common issues that may cause false detections.
  • Disconnect from the Internet or physically unplug you Internet cable connection.
  • Clean out your temporary files.
  • Close all open programs, scheduling/updating tasks and background processes that might activate during the scan including the screensaver.
  • Temporarily disable your anti-virus and real-time anti-spyware protection.
  • After starting the scan, do not use the computer until the scan has completed.
  • When finished, re-enable your anti-virus/anti-malware (or reboot) and then you can reconnect to the Internet.
Note: Not all hidden components detected by ARKs are malicious. It is normal for a Firewall, some Anti-virus and Anti-malware software (ProcessGuard, Prevx1, AVG AS), sandboxes, virtual machines and Host based Intrusion Prevention Systems (HIPS) to hook into the OS kernal/SSDT in order to protect your system. SSDT (System Service Descriptor Table) is a table that stores addresses of functions that are used by Windows. Both Legitimate programs and rootkits can hook into and alter this table. You should not be alarmed if you see any hidden entries created by legitimate programs after performing a scan.

Then check with a few of your contacts to see if they are still receiving anything.
