I have a similar problem I read about earlier in that I have an "option" when installing the free ZA 8, which can't be deselected.
1. the Spy Blocker toolbar, powered by ask.com is selected with a tick. This can't be deselected.
2. after installation I am frequently disturbed by a nag window asking me if I want to know more about other products. I can't switch this off or at least I can't find an option to do this.
On my desktop I have replaced ZA with *** BLEEP *** but don't really want to touch my laptops as I am happy with the functionality.
Is there any way to avoid these two issues?
