Hello All,

I think I need all the help I can get. Thanks in advance for taking the time to read this.

I contracted the Yahoo! redirect virus about a week ago and did the following things:

1)Tried to run Malwarebytes (would not load)
2)Ran SPYDoctor...found a few infected files and removed... the problem didn't go away
3)Got advice to re-name the .exe file for Malwarebytes and did so
- Malwarebytes loaded
- I updated
- Scanned and removed what it found... the problem didn't go away
4)Saw a post on SDFIX and followed the instructions... that didn't work either
5)Saw a post on ComboFIX and against better judgement (sorry)... followed the directions for ComboFIX

The redirect issue went away. I can do a Yahoo! seach without being redirected. However...

1)My computer is extremely slow, especially the internet
2)My computer will shutdown (sometimes instantly, sometimes after a few minutes, sometimes after a few hours)
- especially when the load on the computer is larger (ie. trying to run MAwarebytes again, or doing a disk defragement)
3)When rebooting:
- I see some weird laser-like white lines that thunder across the top of the screen
- It would ask me what mode to run windows for a brief second before it loads windows normally (which it never did before)
4)If I place a CD in, it no longer pops up a window asking me what I want to do (which it did do before)

To add fuel to the fire, I remove/deleted unwanted programs (as I though that would be wise... guess not) using add/remove program from the control panel

As if I didn't do enough... I saw a link to run a clean up, which removes all programs used to removed the virus and ran that as well.


Again, any help is appreciated. My goal is to return the computer to a some-what functional state without formatting. (Normal speed internet searches, run programs, not shutdown on its own).


Thanks again.

This is by design. With the virus spread by autorun, it is recommended not to defeat this
Although Combofix is a good tool, it does not work for all things and you are still infected
Let's first try SAS
---------------------------------


ATF
Please download ATF Cleaner by Atribune & save it to your desktop.
  • 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 browser click Firefox 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.
  • If you use Opera browser click Opera 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.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

------------------------------------

SAS,may take a long time to scan
Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.

Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.

  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. 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 menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • 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.
