How do I remove the start search us.com search engine from firefox?

http://start.search.us.com/v/2/?guid={57D051C3-199E-4DE4-9AC7-5694B9254CC9}&serpv=5

When I open Firefox it reverts to the above linked search engine.

That link is to the search engine that has infected my firefox. I have tried several methods to get rid of it. I have gone into extensions and deleted anything that looked like it. I have gone into 'uninstall programs' and un-installed anything that was to do with it. I have ran my Norton 360 scan which has detected nothing. I downloaded Malware Bytes free anti-malware software scanner which detected nothing. I have reset the home page to default but this does nothing. I have tried re setting firefox, no result. Please can you help me remove this search engine off firefox, nothing seems to work and it is very irritating. Thanks

Such hijackers come with freeware/shareware program, which installs 2 components : The hijacker "extension" itself, which changes the browser settings and some sort of legitimate browser settings freezer, that keeps the settings that way. So, when you uninstall the extension, the settings remain frozen (or revert after browser restart). What you need to do, is to uninstall the second component from control panel. It might be named browser protect or similar, there are many versions. Try running Adwcleaner, Junkware removal tool or spyhunter , they might identify which program freezes the settings. Source.

You can check for problems with preferences and rename or delete the prefs.js file and possible numbered prefs-##.js files and a possible user.js file to reset all prefs to the default value.

Re: How do I remove the start search us.com search engine from firefox?

hello Pondi, there are two things that need your attention:

  1. there's a user.js file present in your profile folder, which is often used by adware to override your custom preferences. in order to fix that go to firefox > help > troubleshooting information > profile folder - "show folder", then a new window will open up. in this window look out for a file named user.js, in case it is present , delete or rename this file and restart firefox afterwards. How to fix preferences that won't save
  2. the TopArcadeHits 1.0 extension that you've installed is also likely adware. though other users have reported it is difficult to remove, at least keep it disabled: Disable or remove Add-ons

Hey just thought I would say I appear to have fixed the issue. There was a program called 'Wild Tangent Games' that was hiding away, I found it and deleted it. Thanks for all the help guys, I appreciate it. Cheers!

For me, I followed these steps and now it is removed. Other articles suggest some other programs along with the one I discussed, you really don't have to install them.

THIS WORKED.
