<DIV dir=ltr><FONT face=Arial color=#000000 size=2>When the malicious code 
writers build their viruses and Trojans why not code the threats to detect the 
use of proxy servers and if used, connect through them.<SPAN 
style="mso-spacerun: yes">&nbsp; </SPAN>Working in Corporate America, most 
firewall configurations block outbound TCP 80, as&nbsp;the proxies listen on 
other non-standard TCP ports.<SPAN style="mso-spacerun: yes">&nbsp; </SPAN>A 
virus should first check to determine if a proxy is used and if so use that 
proxy to download the malicious code, backdoor, etc.</DIV></DIV>
