I cleaned some trojans off a friend's Windows XP machine but I still couldn't get a Windows Update to load. I can get to the update page, but after clicking "express", the page comes back unable to load.

The history: I couldn't get Malwarebytes to run, so I renamed the executable file as well as the program itself. It would run but then shut itself down. So, I ran it again and I would stop MWB along the way and delete viruses, little by little. Finally, the reports showed clear. She uses free AVG and those reports now show clear. However, I still can't do WU. Also, when trying to boot into safe mode, the blue screen of death appears, if that helps anyone with my problem. I ran ccleaner and deleted all it found. I ran combo fix and I'm attaching that log. I also ran rootrepeal and am posting those results. There were red flagged entries, but was afraid to wipe then until someone says to. Actually, I'm posting two RR logs, both showing "hooked" files. Thanks for any help.

Okay. First off, thanks for the help! I completed your directions and after doing combofix with the script provided, windows update automatically started up in the tray. I finished the stages you suggested and came up with these logs. Let me know how it's looking. Again, thanks!

Remove this folder C:\QooBox if the uninstall instructions don't work and delete Combofix.exe AND check your system time and reset if needed[/indent]



Great, all looks good now.

I'll close your post soon so that other don't post into it and leave you with this information and suggestions.

So how did I get infected in the first place?


[indent]At this time your system appears to be clean. Nothing else in the logs indicates that you are still infected.
Now that you appear to be clean, please follow these simple steps in order to keep your computer clean and secure:

Remove all but the most recent Restore Point on Windows XP

[indent]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".
  
• If the shortcut is missing you can also click on START > RUN > and type in %SystemRoot%\system32\restore\rstrui.exe and click OK
  
• Choose the radio button marked "Create a Restore Point" on the first screen then click "Next".
  
• Give the new Restore Point 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 the Disk Cleanup to remove all but the most recently created Restore Point.
  
• Go to Start > Run and type: Cleanmgr.exe
  
• Select the drive where Windows is installed and click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  
• Click the "More Options" tab, then 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.
  
• On the Disk Cleanup tab, if the System Restore: Obsolete Data Stores entry is available remove them also.
  
• These are files that were created before Windows was reformatted or reinstalled. They are obsolete and you can delete them.

Install SpyWare Blaster

Install WinPatrol

Install FireTrust SiteHound

Update your Antivirus programs and other security products regularly to avoid new threats that could infect your system.
You can use one of these sites to check if any updates are needed for your pc.
Secunia Software Inspector
F-secure Health Check

Visit Microsoft often to get the latest updates for your computer.
http://www.update.microsoft.com
Note 1: If you are running Windows XP SP2, you should upgrade to SP3.
Note 2: Users of Norton Internet Security 2008 should uninstall the software before they install Service Pack 3.
The security suite can then be reinstalled afterwards.

The windows firewall is not sufficient to protect your system. It doesn't monitor outgoing traffic and this is a must.
I recommend Online Armor Free
