Hi, first see if you can remove it: Add or remove a search engine in Firefox.
If you can't, you can try these free programs to scan for malware, which work with your existing antivirus software:
- Microsoft Safety Scanner
- MalwareBytes' Anti-Malware
- Anti-Rootkit Utility - TDSSKiller
- AdwCleaner (for more info, see this alternate AdwCleaner download page)
- Hitman Pro
- ESET Online Scanner
Note that not all removal programs will detect all malware, so you may need to run several or all of them.
After removal you may need to reset your home page and search, which you can do by running the add-on SearchReset.
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.
Further information can be found in the Troubleshoot Firefox issues caused by malware article.
