Am I infected? /Windows Notification Icon Area/

Hi, downloaded a few leaked server setups for minecraft just to mess around and now in my notification area on windows, when i click customize to show more it brings me to the notification area icons and when I scroll down theres a application that says and gives me the option to Show Notificsations and Icon, Hide , or Only show notifications…

When I scroll down there is this:

Winrar Achiver
Deleting .rar and when I click Show Icon and notifications it tells me the process is not active atm

I ran a few scans with diff scanners and a few registry files were infected. I cant seem to get rid of this from the icons area even after unistalling and reinstalling java… along with winrar aswell. it just dosnt go away
