That's interesting.... I had my realtime virus protection, firewall and adware/spyware apps running in the background during download, install and while running P6 - for hours. And none of it seemed to affect the app or the install. tlaloc321 - what virus app etc do you use? I have Trend Micro and Ad-Aware. And my experience has been that they are both highly transparent, never cause me trouble, never eat resources. :] Fish
