Howdy, Starting last night we started seeing signs of malware on one of our computers. The license for the antivirus had expired shortly before and since I wasn't the one using it at the time no action was taken until today, but by that point the computer was starting to freeze and play odd advertisements in the background. After doing a scan with malwarebytes, as well as downloading Avast! and running a scan with that, all indications are pointing to svchost.exe acting malicious. The DDS scan logs are attached, any help removing this trojan would be greatly appreciated. Any other attempt through Avast! or malwarebytes have proven unsuccessful.

Welcome to the forum.

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

Please download and run RogueKiller.

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 (don't run any other options, they're not all bad!)

Post back the report.

Yes, TDSSKiller cleaned out a bunch of malware.

Please do this............

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.

Good :)

Please Uninstall ComboFix:

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

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

Please download OTL from one of the links below:

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

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

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.

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

You have out date Java on the system, older versions are vulnerable to malware.

Please go to your control panels add/remove programs and uninstall these:

Java Auto Updater

Java™ 6 Update 25

Then download and install the latest version Java™ 7 Update 4.

http://www.java.com/...load/manual.jsp <---latest version

http://www.java.com/...d/installed.jsp <---verify your Java

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

Any questions...please post back.
