Spam software installed that can't be removed from FIrefox

more options

I have accidentally installed a spam software looking like a genuine app (ad link on the genuine website looking like genuine download). This has installed a ton of different spam, marketing and adware apps on my computer, messing up FIrefox, Chrome and IE. All soft is now uninstalled, computer has been scanned with antivirus and antimalware and no threats are found. Chrome and IE are clear with no issues, however Firefox is still redirecting websites to add sites and adding spam ads to almost every page. There are two extensions installed, which are Adobe and Oracle (both disabled) and some Add-onns but all look genuine (Office, Cisco codec, flash Adobe, Foxit and Silverlight. I have already reinstalled Firefox twice with no success and to be honest I have no more ideas on how to remove this application. Could you please help?

What did you use to scan for malware?

This is our recommended batch of "tools" to use. You may need to use them all.


Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one. Windows 8 has antivirus built-in already.

In Firefox - open up Help > Troubleshooting Information and in the upper-right corner use the Refresh Firefox button. Then restart Firefox.

That didn't help with the issue. Pages are still being redirected with lots of adds on websites like BBC.

I use MS Endpoint antivirus - it doesn't find anything. Malwarebytes didn't find anything either, nor Bitdefender online. No luck with AntiRoot soft. I have however traced it back to software and after quick search otherwebsite also suggested AdwCleaner as best software to remove Adware. It has found number of registry entries, folders etc, but nothing in the Firefox itself, however that seemed to have resolved the problem. Thank you very much.

I am just surprised to see how good software can omit adware.
