THEN

Download and Install Combofix

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

  • IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

[*]Double click on ComboFix.exe & follow the prompts.

[*]When finished, it shall produce a log for you.
[*]Please include the C:\ComboFix.txt in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

FINALLY

run farbar service scanner

Hello,

Here is the results from the afformentioned. Update: Still getting a lot of random alerts, just completed full scan with malwarebytes, no infections. Some random audio advertisements while not using browser. Sometimes firefox will refuse to load any page and i have to restart it a few times until it works. Sometimes when clicking on results from google searches i am brought to a clicktogetresults page which is not the corect address i am trying for, and then the browser fails to contact any sites and i must restart firefox.

Thank you for the help

Did you run that from the recovery console (repair my computer command prompt) ?

Could you download a fresh copy of TDSSKiller to your desktop but do not delete the old copy

Then try TDSSKiller again (New copy)
