Javaupdatedownloader virus!!! help

I want to know its false positive or inocent virus?

 

I got this but NIS 2010 Is removed well I think so,  because this virus is sent to quarantine  :smileyindifferent:

But When I do a full scan say my computer is clean

 

so I want to know its real clean , I dont want install Malwarebytes because is to junk software to my pc

 

Please let me know its real sufficient to scan only with NIS 2010 Thank you
