Hello, all,Hijacked by Uplayer - how to remove

Hello, all,

 

I am running Windows Vista and Firefox browser.

 

I clicked on what appeared to be an official Adobe Flash link. Now a program called Uplayer is  on my computer. Program Uninstall has not removed it; when I try, the program says "Preparing to uninstall" for several minutes, then disappears..  Norton Internet Security, Adwcleaner, Junkware Removal Tool, Malwarebytes, and HitmanPro have not detected or removed it.

After my regular homepage, my Firefox  browser is transferred to a search engine I have not heard of. I tried to uninstall in Safe Mode, and got a message that the Windows uninstall program was not available.

 

Please help me remove this nasty piece of work.
