<br /><br /><br /><br />No stupid question at all.<br />My understanding is that a local machine port is used by a product such as Avast and others to examine mails or web pages. Then through that local port the Avast product connects out to the internet. All nice and safe really. BUT, you need to lock down that port only for the applications that need internet access. Otherwise some trojan can come in in form of an application and will tunnel right smack through the port to the outside. So if you have a firewall you set up permissions for several applications to be allowed to use that local port and no other application could tunnel through. You'd allow email client or a browser or anti-malware update to use that port. All other applications will be blocked. I hope I got it right in this explanation <img src="http://www.bleepingcomputer.com/forums/style_emoticons/default/smile.gif" style="vertical-align:middle" emoid="" border="0" alt="smile.gif" /><br /><br />On second thought, perhaps I'm complicating things. I don't know. Maybe if you specify which applications are to be watched by Avast it might be sufficient. I've read a bunch of websites discussing the need for careful setup with local proxy ports, so that's where I'm coming from.<br /><br />
<br />Thanks Tos,..........................this may be a stupid question, but what do you mean when you say it needs to be locked down n the firewall?<br />
