A-NSISU Is not just a spyware
I got it yesterday and it overwrited some system32 files, created a new dir system32/vchost with in vchost.exe (fake) and ....ocx (i do not remember) , launch vchost.exe (its) from the run of registry , shut down Norton AV (updated), don't let start MS recoverig system , and crash my system.... ahh.. I forgot, most of antivirus, anti spyware don't see it (I tried), only ArcaVir and nod32 do.
I think it's enough to be considerd a virus.
I cleaned what I found (alone) but it's not enough.
Explorer still doesn't work correctly, AV doesn't start ..and so on.
Bye
