How can I block Yahoo.
Although I have removed Yahoo from my list of search engines every time I click the home tab it takes me to a Yahoo page. How can I stop this.

This could be an issue caused by AdAware or Web Companion from Lavasoft. Please uninstall it of you have it Programs and Features.
You can look for a file named dsengine.js in these locations. You should only find channel-prefs.js in the "defaults\pref" location. Any file found here apart from channel-prefs.js is suspicious. You can check the content of the file in a text editor (use open with and do not double-click the file).
C:\Program Files\Mozilla Firefox\defaults\pref\ C:\Program Files (x86)\Mozilla Firefox\defaults\pref\
You can look for a file named dsengine.cfg in the main Firefox program folder.
C:\Program Files\Mozilla Firefox\ C:\Program Files (x86)\Mozilla Firefox\
Delete the dsengine.js and dsengine.cfg files when present.
Please use one of these like ADWcleaner 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 (for more info, see this alternate TDSSKiller download page)
- AdwCleaner (for more info, see this alternate AdwCleaner download page)
- Hitman Pro
- ESET Online Scanner
Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista if you don't already have one. Windows 8/10 have antivirus protection built-in.

It might be that Yahoo was set as your homepage.
