You only open those ports to a few IP's (symantec.com) or if your firewall can use DNS, then you can get more specific. So it would be possible for a person to browse symantecs site, but that would be all they cloud see. If the FW does dns then all they could see is the update url from symantec.<br />

Hi all,<br />
<br />
For company policy, we have 3 PCs no Internet access but still have network connection to server. That 3 PCs also have installed NIS 2011 .<br />
<br />
I understand Norton Internet Security need to have Internet access for Liveupdate.<br />
If we want to get that PCs for Liveupdate how to setup the rule on the firewall ?<br />
<br />
e.g. &nbsp;port forward from any to <a href="http://www.symantec.com" rel="ugc">www.symantec.com</a>&nbsp;<br />
<br />
Thanks,

Anti-virus software was originally developed to detect and remove computer viruses. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats. In particular, modern antivirus software can protect from malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious layered service providers (LSPs), dialers, fraud tools, adware and spyware. Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity theft (privacy), online banking attacks, social engineering techniques, Advanced Persistent Threat (APT), botnets and DDoS attacks.

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.
