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?

You should do the following:
Scan your Computer for Malware
- MalwareBytes' Anti-Malware
- TDSSKiller - AntiRootkit Utility
- 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.
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.
Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Thanks for that advice tylerdowner. I did it and it seems to have worked. I still don't know how this malware appeared. Must keep an eye open for it in future.
