My desktop is sadly infected with some ugly trojans. It's WinXP home with SP2. I have AVG 7.5 free antivirus software, SUPERantispyware free edition, and Spybot search and destroy. SpywareBlaster is also installed on the computer, but I don't recall installing it and didn't run it. I ran scans using the first three. All three found and supposedly "fixed" infections ranging from adware/spyware to trojans.

The problem has been going on since last spring, but the desktop computer isn't used that often (I use laptop mainly). There were three users listed for the computer. When my husband logged in on 9-5-08 he said his background went white and his start menu became very, very limited. He also had an incredible pop up problem, mostly porn. I witnessed this when I logged in last night to try the virus scans. The options for nearly everything on the start menu was inaccessible (as in not there). You couldn't access and programs, the control panel, my documents, my computer or anything. I could access internet and then put c: into menu to view my computer and try to locate the file the scan indicated was infected. If necessary, I can c&p the log files of those scans for information. I do know there were additional icons on his desktop (These weren't on my desktop, only his). I deleted them manually (they said they were antispyware etc). According to one scane, it appeared there was a folder/program called PCHealth with one file named 5.exe that was infected or the source of infection. When I tried to do alt-control-delete to pull up taskmanager, I was told I was denied that privilege by the administrator, but I know his user had administrative rights. I ended up logging in under my user (which seemed to have less problems) and deleted my husband's entire user account using control panel/user accounts. I realize that likely didn't fix anything, but I did make the choice to delete all files while doing so.

The scans I ran today were done using my user-the only remaining administrative user for the computer. I didn't check my daughter's user to see if anything was going on there, but she has her own laptop, so I can remove her as user if that makes things easier.

SUPERAntiSpyware lists the following items in quarantine:
Adware.Vundo Variant/Rel
Adware.Vuno.Variant/Resident
Rogue.Dropper/Gen
Trojan.Net-MSV/VPS-Variant
Trojan.Dropper/Gen-Zero
Trojan.Unclassified/GTS

AVG lists a number of Trojans, dating back to April, which is when I got rid of Norton and installed the AVG.

The most apparent symptom is the popups or opening of whole new browzer windows. I haven't done much with the computer other than attempting repair (as mentioned above) so I don't know if those symptoms persist.
I did discover that after running SUPERAntispyware it required a restart, and after the restart I ran it again and it still came up with three infections, so I restarted again, ran it again, and it still had those, which makes me a big ASSUMER that they're reinstalling themselves or the program isn't really fixing them.

So, that's what I know. Can anyone help? I've used up all my computer knowledge--and then some.
Thanks in advance.

This is a very badly infected PC and it has been infected a long time. The malware has a good grip. It will probably take several update and rescans to try to clean it. A format and reinstall of the OS may not be out of the question.

So run the SUPER from safe mode again.

Download Attribune's ATF Cleaner and then SUPERAntiSpyware, Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opers browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.

Follow With:
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.

FIX Task manager:
This step involves making changes in the registry. Always back up your registry before making any changes.

Go to Start Run and type: regedit
Click OK.
On the left side, click to highlight My Computer at the top.
Go up to File Export
Make sure in that window there is a tick next to "All" under Export Branch.
Leave the "Save As Type" as "Registration Files".
Under "Filename" put RegBackup.
Choose to save it to C:\
Click save and then go to File Exit.
Or you can download and use ERUNT which is an excellent free tool that allows you to to take a snapshot (backup) of your registry before making changes and restore it when needed.

Click on the link below:
http://www.kellys-korner-xp.com/xp_tweaks.htm
Scroll down to #275 and click "Lift Restrictions - TM, Regedit and CMD" in the left column. Go to File, choose "Save page as" All Files and save regtmcmdrestore.vbs to your desktop. Double-click on that file to allow the script to run and reboot when done. Since the script modifies certain registry settings your anti-virus package may warn you about it. Ignore the warning and allow it to run.

Yeah it's a good thorough tool. You look clean.
If there 's no more signs of the infections then....

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.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.

Sorry for the delay in responding. Wanted to thank you for your help. I've followed your advice and created the system restart point and then "cleaned up". I'll continue to monitor this and create new post should it appear any traces are still there.

Thanks again!
