Hi sawt,
Repeat again: you can report a FalsePositive here:
http://www.avast.com/contact-form.php?loadStylesBlacklist could also have been for the IP not just your domain.
In the case of a false positive avast is known to react soon and unblock...
You'd rather protect tour site so your full.php?ID=4867&title=باÙÙÙدÙÙ.
is no longer vulnerable to shell code scripts of any sorts, like e.g. Full PHP Emlak script,
you know from the incidents which sites tried to attacked you...
Protect also against this for instance:
http://www.cvedetails.com/cve/CVE-2013-1635/also get removed from the blacklist at cbl.abuseat dot org
Stay safe and secure, is the wish of,
polonus
