it was the searchqu add-on extension. I disabled it.
Every time I start my web browser (mozilla firefox) my homepage gets hijacked to searchnu.com.
I reset my homepage to my.yahoo.com, which is what I want it to be, and save it.
Alas I start firefox again, and again searchnu.com is my homepage.
How do I get rid of it. My virus software doesn't identify it. It's not in my add/remove software list. Help!!
