Why is firefox searching with Yahoo! When I have eliminated ALL search engines except for Google??
I went to search for something and Yahoo! came up as the search page, even though I have taken out every search engine except for Google, my preferred search engine. How is this possible??
Additional System Details
- User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.101 Safari/537.36
Hi ! Yahoo Search is a legitimate search engine, but you may be dealing with search.yahoo.com, which is a browser hijacker, malware that you of course want to get rid of.
Go to the 3-bar menu (or 'Tools') => Addons => Extensions and look for any unfamiliar or suspicious looking extensions, like e.g. :
SafeSearch Incognito SearchAssist Incognito Search for Fire Fox 1.6 SafeSearch ch SafeSearch net File Convertor and Search Addon
When you find any : remove them.
Do the same in Windows' Control Panel => Programs.
However : most malware will be 'hiding' somewhere , so let's run malware scans :
Further information can be found in this article :
Run most or all of the listed malware scanners.
They all work differently - what one program doesn't pick up, the other might.
I've done these checks and Yahoo is STILL defaulting when I have not selected that - my Firefox default is Google!!! I use NOD32 by Eset and it has not detected any malware. How do I change this??? Uninstall and reinstall Firefox perhaps? Thanks, John
This could be an issue caused by AdAware or Web Companion from Lavasoft.
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.
