Hello, bleepingcpmputers,


Long time lurker, first time poster.


I was recently infected by a Trojan, and after performing a number of scans and registry edits it appears that I've managed to remove it. However I'm still unable to use any of my installed browsers, currently:


  • Mozilla Firefox and thunderbird crash on start-up.
  • Internet explorer gives the "this webpage cannot be displayed" page. Previously it displayed a dialogue box reading something like "browser cannot load search engine" but this is no longer occurring.
  • Chrome gives "this webpage cannot be displayed".

The only exception to this is when I open internet explorer via links present in RougeKiller, after which I am able to browse to any page (including search engines).


Using the elevated command prompt I have tried resetting all the associated DNS files and host files to no avail. Antivirus, malware and registry cleaning programs I have run include:


  • Malwarebytes
  • SUPERAntiSpyware
  • Adwcleaner
  • aswMBR
  • ComboFix
  • CCleaner


I have also cleared all temporary files several times and have reinstalled Firefox after uninstalling it and deleting the folder stored in "appdata".


At this point I am considering a clean install but this laptop did not come with a windows 7 disk, so the only option I see available is an upgrade to Windows 10, which I will do if necessary (but would rather not otherwise).


Windows update is functioning and all malware removal software are currently able to update their databases, so I know the internet connection is working otherwise.


This all started while I was trying to install drivers to get a Bluetooth dongle working with apt-x, but at this point I think that's a separate issue.


Any help would be much appreciated, thank you!

You can download a Windows 7 ISO if you have the 25 digit product key from Windows 7


You should be able to request an Install DVD or CD from the manufacturer...there may be a fee for that depending on the manufacturer.

From an ELEVATED command prompt type:

netsh int ip reset

Press enter

See if that works
