I recently ran Combo Fix to get rid of a virus after the direction of someone from Geek Squad and it worked. It deleted the virus but it also deleted everything else of use on my computer. I lost my ACT! contact database, VPN Connection files, all of my Outlook emails, and Microsoft office programs.

After a reboot a ran a file search and Combo Fix is still on my computer in the Qoobox as well as a txt. file of all of the quarantined files that it hard deleted.

Can anyone please advise me on if/how I can recover these files without me having to go through the files line item by line item to remove the .vir titles? I could really be bleeped if I lost all of these work files for good!

I just started running the system restore program and it appears to be working because there's some icons starting to pop back up on my desktop that were gone before. It's to my understanding that this restore will also bring back the virus that I was originally trying to get rid of. Is there a way to identify and delete the virus from my computer manually? It was a virus that would hijack my web browser programs and redirect them randomly. I have my combo fix log if that would be of help.

OK ,unfortunatrly since as you found out CFix isn't to be run without supervision as it can really screw a PC. That said the Log would need to be read in our HJT forum. Now that will be a couple days do to backlog. So choice is I give you instructions to post there or we see if we can just clean it here.

For choice 2...
Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.

alternate download link

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.


Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
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 Opera 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.

Installed the next two steps to my infected computer but I cannot enter into Safe Mode. Windows will not accept the login password. Per your instructions, I'm informing you and continuing on in normal mode.

Yes run in normal as it may find the blocking malwares.


SUPERAntiSypware has a built in "Repairs" feature to fix policy restrictions and certain Windows settings which are sometimes targeted by malware infection. To use this feature, launch SUPERAntiSypware.
  • Click the Repairs tab.
  • Click on (highlight) "Repair broken SafeBoot key" and then click the Repair button.
  • You may be asked to reboot your computer for the changes to take effect.
