*HELP* - Cubase 8 VST's not opening in 64-bit

After I cleared a virus that was on my computer, Kontakt 5 & Battery 4 stopped opening in 64-bit… thoughts/solutions regarding this dilemma???

Was the virus by any chance the hack that enable that software to work.

My solution would be to start using Groove Agent instead of Battery, Kontakt replacement, not sure!
