Site Blocking issues under Windows 7 SP1

It seems that the Site Blocking does not work on my computer? Any one has met this problem?
Any proxy or VPN even OperaTurbo has disabled, and I tried different browsers, but Avast! Site Blocking model does not work:

My system, Windows 7 SP1(New system, reinstalled just few hours ago).
Anyone has good ideas?

Me too,

My desktop is deep XP.

It's can'tBlock the IP list.

why?

Herllo!Anybody here?

Try entering sina.com.cn in one line and soho.com on another and try again.

type in this to block all .com websites:
http://.com

Or just disconnect from the internet. ::slight_smile:

That particular mask works fine for me… don’t you have just too many entries there? I’d guess the buffer doesn’t have an infinite size…

???

Well, I tried to clear all entries, and use this mask, and still not work, I think maybe this module didn’t work in my system.

And I try this in a virtual machine, and this mask works well. So…I really confused about the reason caused this problem.
