The protection for the programm is good indeed, i've got a license for 3 Computers, i've had no software conflicts either except for the fact that for a short period of time, Command&Conquer Generals was partially recognised as a virus..
But, that flaw was quickly removed form the virus definitions..

Thye GUI needs an upgrade indeed, but on the plus side of this GUI is that you can actually add, or remove some of the quick links/features in the Scan/test-GUI & and the Programm-overview..

as for the compatibibilty for the e-mail scanner, i'v e got no experience excpet with outlook, express and livemail, but it worked fine..

The performance of the scanner/package as a whole is indeed impressive, as you can modify the testing of the virusscanner to your computers needs/specs.
At this point there is even a manual @grisoft online that guides people trough usefull settings with weak(er)/old computers..

I've been so anxious about the next version (8.0), that I could get an Powerpoint presentation with a summarisation of the new and better features.. :D Since some family members needed new security programm's for their systems, and I wanted to know whta features would be included!
