You can use:

acl blocksites dstdomain "/etc/squid/blocks.sites.acl"
http_access deny blocksites
deny_info TCP_RESET blocksites

And in your "/etc/squid/blocks.sites.acl" file, you can have something
like the following:

.viruses.com
.adaware.com
.bansite.com
.malsites.com
.chatsites.com

Note: Using dstdomain over url_regex is recommended. Your deny rules
should also come before your allow rules too!

Keeping that it mind, it should work.

Hope that helps.

Thanking you...
