Hello, Ive been spending a few hours trying to remove www-search.net by Tuvaro, this pops up every time I open firefox as default search engine. Ive run malwearbytes, comodo, rougkiller, tdsskiller, reinstalled firefox ect. I have not found an extention for it on firfox and its not my default page and its not in add remove programs and I cant find it searching my hard disk. A blank black.exe box pops up periodically and started the same time the www-search.net by Tuvaro took over my web browsers firfox and chrome. I have followed all the instructions from http://malwaretips.com/blogs/www-search-net-removal/ to no avail. Any help would be greatly appreciated. Sinbowden
