win32,za (not a virus) hehehehe

If they want to run scareware adverts then label it scareware.

There are dozens of paid and free firewall solutions that do not use these type of adverts.

My opinion, Nod32 paid or avast / comodo free. Just a personal opinion as neither of these tell the users there infected with a global threat - in fact it might be fair to say these alternatives are too busy protecting users to stoop to industry wide recognisable scareware.
