First, thanks for your help.

My computer was crashing upon starting. I was able to download Malwarebytes and run a scan. The scan was able to remove everything; however, svchost.exe keeps returning. This results in Malwarebytes periodically having to block it as the computer runs. The latest scan shows 2 svchost trojans. The log is atttached, as are the dds logs. Any advice on how to remove the viruses and prevent theirr return would be great.

Again, thanks for your help.

Welcome to the forum.

Please remove any usb or external drives from the computer before you run this scan!

Please download and run RogueKiller to your desktop.

Quit all running programs.

For Windows XP, double-click to start.

For Vista or Windows 7, do a right-click on the program, select Run as Administrator to start, & when prompted Allow to run.

Click Scan to scan the system.

When the scan completes > Close out the program > Don't Fix anything!

Don't run any other options, they're not all bad!!!!!!!

Post back the report which should be located on your desktop.

Please read the directions carefully so you don't end up deleting something that is good!!

Please note that TDSSKiller can be run in safe mode if needed.

Please download the latest version of TDSSKiller from here and save it to your Desktop.

  • Doubleclick on TDSSKiller.exe to run the application, then click on Change parameters.

  • Put a checkmark beside loaded modules.
    2012081514h0118.png
  • A reboot will be needed to apply the changes. Do it.

  • Check all boxes then click OK.
    clip.jpg
  • Click the Start Scan button.
    19695967.jpg

    Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
    62117367.jpg
    Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.
  • A report will be created in your root directory, (usually C:\ folder) in the form of "TDSSKiller.[Version]_[Date]_[Time]_log.txt". Please copy and paste the contents of that file here. There may be 3 logs > so post or attach all of them.

Here's a summary of what to do if you would like to print it out:

Run TDSSKiller again and choose Delete for this one only: (no need to check the Loaded Modules" box or post the log)

17:03:46.0589 2444 \Device\Harddisk0\DR0 ( TDSS File System ) - skipped by user

17:03:46.0589 2444 \Device\Harddisk0\DR0 ( TDSS File System ) - User select action: Skip

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

Then.................

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.bleepingc...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.

Thanks again Mr. C.

Scan shows nothing. I am also not getting the message from Malwarebytes that is stopping a malicious process.

I am confused about how the virus got deleted though. When we first ran the TDSKiller application it detected the Harddisk issue, but not the second time. However, now everything seems good. When was it removed?

I appreciate all the help.

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

Lets check the system for any adware..........

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

  1. Right-click on adwcleaner.exe and select Run As Administrator 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.

That looks OK......

Lets check your computers security before you go and we have a little cleanup to do also:

  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.

Java™ 6 Update 25 <----please uninstall from add/remove programs

Java version out of Date! <--------Download and install the latest version from Here

Adobe Flash Player 10 Flash Player out of Date! <-----please check for an update

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, etc....

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

Any questions...please post back.
