When I click on new tab on Firefox delta search loads.I have tried by all means to remove it but am unable to remove it.

Its a little extreme, but I just tend to reset firefox and reinstall my extensions. This will not affect bookmarks, cookies or anything important, and will create a set of backups in any case on your desktop. I do this semi regularly for a less computer savvy family member who seems to get various search engine hijacks every so often, and it always works

Reset firefox to its default state.

Reinstall any extensions you actually need again

A thorough scan with a good updated AV and something like MBAM is also recommended. – Karan Apr 11 '13 at 12:35
Yeah, I guess. I have both on my dad's laptop. I have to deal with this sorta the every month or so, and just setting the default search either does nothing, or breaks something else. I kinda take the AV and MBAM for granted. – Journeyman Geek Apr 11 '13 at 12:43
The advice was obviously meant for the OP and not a geek like you. :) I sympathise with you though - this is something all of us who do free tech support for clueless relatives and friends have to face quite often. – Karan Apr 11 '13 at 12:45
Well, for now, it pays for school, technically and i can't learn as much if things don't break ;p. I'm more mad at whoever thinks its perfectly fine to hijack someone's search engine, and install a whole load of unwanted garbage. They need to find honest work, like loansharking, and mugging babies for lollypops. – Journeyman Geek Apr 11 '13 at 12:49
Ha, although I'm sure you'd find babies being mugged galore if it was as profitable. :/ – Karan Apr 11 '13 at 12:53

It probably changed Firefox's preferences, so you will have to reset them manually.

There's a removal process documented here:

And one more thing, make sure you removed the culprit; otherwise, I'm afraid the Delta Search nuisance may return. If you don't know where it came from, use AdwCleaner.

P.S. it's actually amazing how this "search engine" made its way to top 100 sites in just a few months. I suspect black magic :)

Your first link seems the slightest bit dubious - specifically the tool that's been recommended. ALL the malware removal 'tools' are the same one, and it seems to be using what seems to be a dodgy referral/affliate site. – Journeyman Geek Apr 14 '13 at 6:02

Go to "about:config". Search "Delta". Right-click each entries and click "Reset". See detail from here

Steps to remove Delta Search from Firefox new tab:

  1. Enter about:config in Firefox address bar
  2. Search browser.newtab.url
  3. Right-click then click "reset"

Now you'll see value as about:newtab...

That's it; you have successfully removed the annoying Delta Search engine page when you are opening a new tab.
