Let me just preface this by saying as a longtime computer user I'm not generally one to get viruses. I made the unfortunate mistake of lending my laptop (the infected computer) to my dad for the past week or so only to get it back and find it with a virus so I don't entirely know how it got here or when the incident of infection occurred.

I got my computer back last night and when I booted up I received an error message that I can't exactly remember but may be able to replicate if necessary. Everything else appeared to be functioning correctly so I figured it was a one-off thing; I went on Facebook briefly then went to sleep. When I woke back up the next morning my MSN chat logs had indicated that I was sending out messages with an obvious fake myspace link indicating that I was sending out a virus via MSN. Then, about fifteen minutes after noticing this the virus locked up my mouse and keyboard and started opening MSN windows one by one and sending out the message again; before this became problematic I quickly shut down the computer (using the power button). I restarted and uninstalled MSN with the intention of ensuring that it couldn't propagate like this again. I then downloaded and ran AVG Free which is still (very slowly) scanning my PC. So far it has found:

Backdoor.Turkojan
Backdoor.IRCbot.GCT (And a registry key associated with this)
Trojan Horse Generic11.BGKE (It found this in a temp folder which is unusual because I just wiped my temp folders)
Trojan Horse Delf.DZN

So I come to you, a lost and confused computer user, for help. I would greatly appreciate any advice.

I'm on Vista 64, by the way.

Welcome to BC

Please download Malwarebytes Anti-Malware and save it to your desktop.
  • 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, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

Your log looks clean. how's it running?
--------------------------------------

If there are no longer signs of malware then please....

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok"
  • Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" Tab.
  • Click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
