Any Trend Interscan Viruswall users?

[Mark M]

Ive got a fair few sites blocked but when I started to add some recently they arent being blocked. Ive had a look on the Trend website and it says that there is no limit to the number of sites that can be blocked.

Its strange though as if I try a site from higher up the list it will be blocked bu the more recent ones aren't being blocked.

Any ideas?

Thanks, Mark
