it is really a hard work to add one by one… >:( just a little hope …i use it to block ads…
No, there isn’t such a feature.
Adblock Plus 1.3.2 https://addons.mozilla.org/en-US/firefox/addon/1865/
Super Ad Blocker 4.6 http://download.cnet.com/Super-Ad-Blocker/3000-7786_4-10295147.html
cause nod32's web control has a feature like that can block ads....i don't like add-on ~~~~~ :P
I know that so i hope avast can add this feature …it do not take that much work…
Avast doesnot have it…if you think that it is a effective feature post it on wishlist or use addon…
why you avoid addon?does their any problem…many people use adblock plus & it is also very popular addon for firefox…
first i dont use firefox....i use ie most of the time. chrome second...though i know chrome has an addon ,i dont like it...
and i should say it is more effictive to block ads directly by usl in china or you’ll be tired of pop-up ads it is really annoying… …
Or may be you can add it to hosts file?
though NOD & kaspersky have this feature…but it is not a antivirus replated things…if you doesnot like chrome addon then use opera or IE…but why you found it on avast?
well i know that should work …avast IS offers a feature (anti spam$blockers) then why dont use it?and question is thatsince avast offer site block feature why not just go just a little further… i am tired of typing urls one by one…just hope can ad a button to import from a file 
well you know that avast is offers a feature named (anti spam&blocker) yeah? from there we can block access to unwanted urls.and i just hope avast can ad a button to click to let me import from a file in stead of type urls one by one…
and i just dont like addon…really i just dont like… :-\
so it is better to post it on wishlist forum…the tech team will think about it that it should possible to add or not & is it useful or not
ok。。。。。tks
