After installing a program called "FreeFileViewer", the program disabled access to Firefox's "Get add-ons" and "Extensions" options. To make matters worse, it installed the Yahoo! toolbar that I now can't remove (because it disabled Firefox's options to do so).

Please help. Any advice you can give me to restore these Firefox options would be greatly appreciated!

BTW, I am running Firefox 15.0.1 on a Windows 7 machine.

This program install an other program called InstalllQ, an adware from the site w3i.com which is the source of the problem.

FYI:

Web Of Trust rating for w3i.com: WOT rating w3i.com

The solution:

1) Download and install RKill form Bleeping Computer and run it:

RKill download Web page

2) Download (from the official Web site), install, update and run MalwareByte

Official MalwareByte download Web page

Normally this is enough to fix the problem.
