I had no problem a couple weeks after its release.
But then I run a clean machine, ZA firewall, Norton AV, 3 spyware killers (AA, PP, SBS&D) and I never open junk.
The worst websites for trojans and spyware are not porn.
They are song lyric sites.
I've had it installed on mine for months, no problems.Installed it on two more recently, again no problems.I, personally, am not fond of Windows firewall so I use Zone Alarm but no one else seems to have a problem with it.
