DNSChanger removed - problem still there


Recommended Posts

This started as a DNSChanger infection. Initially Malwarebytes found and removed it. I also manually removed the task and program associated with it. All was well for a day.

 

Now the problem is back, but Malwarebytes comes up clean, as does AdwCleaner and Avast Browser Cleanup. Did a few reboots, etc.

 

Current FRST.txt and Addition.txt attached.

 

Interestingly, the problem occurs in Firefox (using version 43.0.4), but not IE. All add-ons have been removed from Firefox.

 

TIA.

I recommend you totally remove Firefox and start over. Make sure you still have a working Browser available, eg Internet Explorer or similar...

Go here: https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer and follow those instructions...

Ensure when the uninstall completes to navigate to and delete the firefox installation folder (if present):

(32-bit Windows) C:\Program Files\Mozilla Firefox
(64-bit Windows) C:\Program Files (x86)\Mozilla Firefox

It is essential the installation folder is removed. Re-boot your system when that is completed....

Next,

To remove all remaining data and profile information...

    Press "Windows key + R" to open the Run box
    In the Run box, type in or copy and paste %APPDATA%
    Click OK.  A Windows Explorer window will appear.
    In this window, choose/open in succession Mozilla > Firefox > Profiles.
    Select Delete on each entry in reverse, eg  Profiles > Delete. Firefox > Delete. Mozilla > Delete.

 

Re-boot your system when complete!

Next,

Go here: http://www.mozilla.org/en-US/ download and install the latest version of Firefox...

Next,

When Firefox is installed and open select these keys together :- Ctrl - Shift - A that will access Addons manger, this gives access to find addons, use, start, stop or disable those features etc....

Ensure to use Addons manager to search for and install the following:

 

AdBlock plus

Flashblock,

DrWeb Anti-Virus link checker

DrWeb Scan Link

 

plus any other addons you normally use.... Now try surfing, see what happens...

 

Next,

 

Download tfc_icon.png TFC to your desktop, from either of the following links

  •  

     

  • Save any open work. TFC will close all open application windows.

     

     

  • Double-click TFC.exe to run the program. Vista or Windows 7 users accept the UAC alert.

     

     

  • If prompted, click "Yes" to reboot.

     

     

 

TFC will automatically close any open programs, including your Desktop. Let it run uninterrupted. It shouldn't take longer than a couple of minutes, and may only take a few seconds. TFC may re-boot your system, if not Re-boot it yourself to complete cleaning process <---- Very Important
 

Keep TFC it is an excellent, run weekly utility to keep your system optimized, it empties all user temp folders, Java cache etc etc. Always remember to re-boot after a run, even if not prompted

 

Next,

 

Download "Delfix by Xplode" and save it to your desktop.

Or use the following if first link is down:
