Hi guys, hopefully someone can help me...

I was having some malware problems - noticed my Google results would always bring me to an online shopping website like toseeka.com or shopaholic.com etc - and I googled it and found a post in a support forum from a guy who said that he had the same problem, ran Combofix and it resolved the issue. So I downloaded and ran Combofix while following the guide that I found on this site - yes, I am embarrassed to admit that I ran it without seeking advice here first.

It seemed to work fine; I downloaded and installed the recovery console, ran the scan, it completed Stage 50, etc... But when CF was preparing the log report, I got an error in the CF screen that said "Problem: 7126" and then Windows gave me the system shutdown 30 sec warning. Windows didn't actually shut down, but nothing seemed to be working, so I did a hard boot and crossed my fingers. Windows started but was very sluggish, and within a few minutes it "froze" so that only my Windows background was visible. Couldn't start a task through Task Manager, pressing Windows-E would not start Explorer, etc. I did another hard boot, and now it seems to be working, except that performance is rather sluggish and Firefox is not my default browser anymore... I have noticed that the malware problem seems to have been fixed though! Anyway, just wondering if I should use the recovery console to restore the backup that ComboFix created before I started the scan.

Any advice?


Thanks in advance,

Have you uninstalled Combofix yet?



Uninstall ComboFix

Remove Combofix now that we're done with it.
  • Click on your Start Menu, then Run....
  • Now type combofix /u in the runbox and click OK.
    Notice the space between the "x" and "/".

  • When shown the disclaimer, Select "2"
This will remove files/folders associated with combofix and uninstall it.
----------------------------------

Let's see if you have any leftovers


The process of cleaning your computer may require you to temporarily disable some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs
---------------------------
Be sure to re-enable your AV and malware scan tools if they were disabled

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

Some types of malware will disable Malwarebytes Anti-Malware and other security tools. If MBAM will not install, try renaming it first.
  • Right-click on the mbam-setup.exe file file and rename it to mysetup.exe.
  • Double-click on mysetup.exe to start the installation.
  • If that did not work, then try renaming and changing the file extension. <- click this link if you do not see the file extension
  • Right-click on the mbam-setup.exe file, rename it to mysetup and change the .exe extension to .scr, .com, .pif, or .bat.
  • Then double-click on mysetup.scr (or whatever extension you renamed it) to begin installation.
If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files.
  • Right-click on mbam.exe, rename it to myscan.exe.
  • Double-click on myscan.exe to launch the program.
  • If that did not work, then try renaming and change the .exe extension in the same way as noted above.
  • Double-click on myscan.scr (or whatever extension you renamed it) to launch the program.
If using Windows Vista, refer to How to Change a File Extension in Windows Vista.

Be sure to update MBAM through the program's interface (preferable method) or manually download the definition updates and just double-click on mbam-rules.exe to install. Then perform a Quick Scan in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the report in your next reply.

Note: MBAM uses Inno Setup instead of the Windows Installer Service to install the program. If installation fails in normal mode, try installing in safe mode. Doing this is usually not advised as MBAM is designed to be at full power when running in normal mode and loses some effectiveness for detection & removal when used in safe mode. For optimal removal, normal mode is recommended so it does not limit the abilities of MBAM. Therefore, after completing a scan it is recommended to uninstall MBAM, then reinstall it in normal mode and perform another Quick Scan.

Sorry to take so long to reply, I didn't know anyone had replied to my post...

So it looks like maybe I didn't get rid of the malware after all - Firefox is very slow, and I just had a google results redirect to the toseeka.com website. I'm not getting the PC AntiSpyware 2010 and Antivirus 2010 pop-ups anymore, though.

Anyway, here's the scoop: I uninstalled ComboFix as per your instructions, then ran MBAM, which found no infected files:

Malwarebytes' Anti-Malware 1.41
Database version: 2815
Windows 5.1.2600 Service Pack 2

9/17/2009 10:41:49 AM
mbam-log-2009-09-17 (10-41-49).txt

Scan type: Quick Scan
Objects scanned: 470153
Time elapsed: 13 minute(s), 6 second(s)

Memory Processes Infected: 0
Memory Modules Infected: 0
Registry Keys Infected: 0
Registry Values Infected: 0
Registry Data Items Infected: 0
Folders Infected: 0
Files Infected: 0

Memory Processes Infected:
(No malicious items detected)

Memory Modules Infected:
(No malicious items detected)

Registry Keys Infected:
(No malicious items detected)

Registry Values Infected:
(No malicious items detected)

Registry Data Items Infected:
(No malicious items detected)

Folders Infected:
(No malicious items detected)

Files Infected:
(No malicious items detected)

Should I restart in Safe Mode and run a thorough scan?

Thanks for your help,
