Please run a Threat Scan with Malwarebytes

Start Malwarebytes 2.0..........
Click on Settings > Detection and Protection > Non-Malware Protection > PUP (Potentially Unwanted Program) detections > Make sure it's set to Treat detections as malware
Same for PUM (Potentially Unwanted Modifications)
Quarantine all that's found
Post the log (save the log as a .txt file not .xml)


Then......

Please download and run RogueKiller 32 bit to your desktop.

RogueKiller<---use class="apple-converted-space" for="" one="" span="" this=""> 64 bit systems

    Which system am I using?

Quit all running programs.

For Windows XP, double-click to start.
For Vista or Windows 7-8, do a right-click on the program, select Run as Administrator to start, & when prompted Allow to run.

Wait for the Prescan to finish

Click Scan to scan the system.

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

RogueKiller logs will also be located here:
%programdata%/RogueKiller/Logs <-------w7 span="">
C:\Documents and Settings\All Users\Application Data\RogueKiller\Logs <-------xp o:p="">

________________________________________________________________________________

Download the attached fixlist.txt to the same folder as FRST.exe/FRST64.exe.

Run FRST.exe/FRST64.exe and click Fix only once and wait


The tool will create a log (Fixlog.txt) in the folder, please post it to your reply. 

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

http://www.bleepingc...combofix/dl/12/ 



Please make sure you click download buttons that look similar to this, not "sponsored ad links":

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<---------- font="" nbsp="">
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.

________________________________________________________________________________

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

 Download Security Check by screen317 from HERE or HERE.

     ·         
          Save it to your Desktop.
·         Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
·         If you get Unsupported operating system. Aborting now, just reboot and try again.

·         A Notepad document should open automatically called checkup.txt.

_______________________________________________________________________________

A little clean up to do....

Please Uninstall ComboFix: (------->if you used it<------- span="">)

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 /

Then hit enter. (it may look like CF is re-installing but it's not)
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 or download and run the uninstaller)

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

Download Delfix from here and save it to your desktop. (you may already have this)

·         Ensure Remove disinfection tools is checked.
·         Click the Run button.
·         Reboot
Any other programs or logs that are still remaining, you can manually delete. (right click.....Delete)
IE: RogueKiller.exe, RKreport.txt, RK_Quarantine folder, C:\FRST folder, FRST-OlderVersion folder, MBAR folder, etc....AdwCleaner > just run the program and click uninstall.

Note:
If you used FRST and can't delete the quarantine folder:
Download the fixlist.txt to the same folder as FRST.exe.
Run FRST.exe and click Fix only once and wait
That will delete the quarantine folder created by FRST.
The rest you can manually delete.
