I've got Windows 7 on BootCamp also as a Parallels VM. I am considering replacing the Parallels Internet Security 8.0.0.506, which I understand to be based on (or to be identical to?) Kapersky 2009, by Kapersky 2010. Is that recommended or indeed a bad idea? Like I'm worried if Parallels Internet Security has something extra specific to Parallels in it. To do the replacement, I guess I would go into W7, use Control Panel / Remove Programs to remove the Parallels Internet Security then install the new version. All OK? Just making sure I don't mess it all up...
