Please create a new system restore point before running Malwarebytes Anti-Rootkit if you can.

Download Malwarebytes Anti-Rootkit from HERE

  • Click on the Cleanup button to remove any threats and reboot if prompted to do so.
  • Wait while the system shuts down and the cleanup process is performed.

Please download and run ComboFix.

The most important things to remember when running it is to disable all your malware programs and run Combofix from your desktop.

Please visit this webpage for download links, and instructions for running ComboFix

http://www.bleepingcomputer.com/combofix/how-to-use-combofix

Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Information on disabling your malware programs can be found Here.

Make sure you run ComboFix from your desktop.

Give it at least 30-45 minutes to finish if needed.

Please include the C:\ComboFix.txt in your next reply for further review.

---------->NOTE<----------

If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.

Log from the quick scan! Everything seems to be running very smoothly.

I got to my moms house earlier and she was on the phone with some guy from microsoft explaining to her that he looked on her computer and located the svchost.exe virus and I got on the phone and he said it would be $299 to fix it, I immediately hung up the phone and began looking to you guys for help. What the heck was going on? Was he full of crap? Weve used tons of different programs and there doesnt seem to be a problem?

Thanks so much for your help tonight.

Here's a typical "svchost.exe" problem if you look at the logs from TDSSKiller:

http://forums.malwar...ndpost&p=654055

I don't see it???

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

Lets check for any adware:

Please download AdwCleaner from here and save it on your Desktop.

AdwCleaner is a reliable removal tool for Adware, Foistware, toolbars and potentially unwanted programs.

AdwCleaner is a tool that deletes :

· Adwares (software ads)

· PUP/LPI (Potentially Undesirable Program)

· Toolbars

· Hijacker (Hijack of the browser's homepage)

It works with a Search and Deletion methode. It can be easily uninstalled using the "Uninstall" mode.

  1. Right-click on adwcleaner.exe and select Run As Administrator (for XP just double click) to launch the application.
  2. Now click on the Search tab.
  3. Please post the contents of the log-file created in your next post.

Note: The log can also be located at C:\ >> AdwCleaner[XX].txt >> XX <-- Denotes the number of times the application has been ran, so in this should be something like R1.

Note:

Please look over what was found......especially any folders, we're going to permanently delete it all in the next step....if there's something you may want to keep...please let me know and I'll explain to why it shouldn't be on your system.

If you see AVG Secure Search being targeted for deletion, Here's Why and Here. You can always Reinstall it.

Adobe Reader 10.1.0 Adobe Reader out of Date! <---please check for an update if available or uninstall and download and install Foxit Reader which is less vulnerable to malware and much better than Adobe.

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

You have out dated programs on the system which are vulnerable to malware.

Please update or uninstall them

Info on doing that can be found in my Preventive Maintenance

~~~~~~~~~~~~~~~~~~~~~

A little clean up to do....

Please Uninstall ComboFix: (if you used it)

Press the Windows logo key + R to bring up the "run box"

Copy and paste next command in the field:

ComboFix /uninstall

Make sure there's a space between Combofix and /

cf2.jpg

Then hit enter.

This will uninstall Combofix, delete its related folders and files, hide file extensions, hide the system/hidden files and clears System Restore cache and create new Restore point

(If that doesn't work.....you can simply rename ComboFix.exe to Uninstall.exe and double click it to complete the uninstall)

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

Please download OTL from one of the links below: (you may already have OTL on the system)

http://oldtimer.geekstogo.com/OTL.exe

http://oldtimer.geekstogo.com/OTL.com

http://www.itxassoci...T-Tools/OTL.exe

Save it to your desktop.

Run OTL and hit the CleanUp button. (This will cleanup the tools and logs used including itself)

Any other programs or logs you can manually delete.

IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST, MBAR, etc....AdwCleaner > just run the program and click uninstall.

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

Any questions...please post back.
