Hmm… let me think about it. Are you sure you denied the read rights to the same account you were logged on when you tried to install Antivir PE?
On a second thought it might also depend on the group membership of your account. In my case, my account on which I tried this is an account with administrator rights (other than the standard “Administrator” account). Maybe if you try this with a non-administrator account the read deny will not work because the program can bypass this.
I’ll try to set up a clean VMWare virtual machine and make some tests today or tomorrow (I’ll also try other programs like Avast Home and AVG Free).
