Something called Snap.do has hijacked my browser. How do I get rid of it?

Question

I have used Firefox for years and I never knowingly download unknown software. Recently I have been getting this Snap.Do search screen instead of my usual browser. Does anyone know from whence it came, is it dangerous, how do I get rid of it?
Many thanks

You should do the following:
'''Scan your Computer for Malware'''
* [http://www.malwarebytes.org/mbam.php MalwareBytes' Anti-Malware]
* [http://support.kaspersky.com/faq/?qid=208283363 TDSSKiller - AntiRootkit Utility]
* [http://windows.microsoft.com/MSE Microsoft Security Essentials] (A good permanent anti-virus if you don't already have one)
Further information can be found in the [[Troubleshoot Firefox issues caused by malware]] article.
'''Reset Firefox'''
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
