Download a crack file another day. Didn't pick up anything with NIS after I finished the download.
Got a 'start.exe' file with it. which look very very suspicion!
So I scan it with NAV and try to delete it with NAV.
But it shuted down NAV intead.
I had to restarted my PC and scan with NAV again to cleaned it up. No problem now.
If U can't trust any file, don't open it.
But part of the fun, is cleaning up afterward.
