Hello, Just today my users reported that AVAST is starting to warn and block my websites.
This is the warning message.

Hi Burn, welcome to the forum 
It seems that avast! is alerting on a javescript file that has a very link link:
18/01/2011 21:19:38 hxxp://forum.animeserv.net/public/min/index.php?ipbv=31005&charset=UTF-8&f=public/js/ipb.js,public/js/ips.quickpm.js,public/js/ips.forums.js,cache/lang_cache/2/ipb.lang.js|>{gzip} [L] HTML:Iframe-inf (0)
In this javascript file (ipb.lang.js) there is an iframe that points to a site that is blocked by the network shield, this is causing the alert.

Thanks for the reply.
This is another warning from a subdomain,

Can you please track it.
I can’t get that alert…
What I would suggest to you is to check your site from top to bottom for changes, as it is probably not just in one location.
