firewall

[George Toft]

Because I had outgoing rules defined, I actually found out I had an 
infected Windows 98 box (yeah - long time ago).  Said Win98 box was 
running a leading AV program and was infected by one of the most popular 
viruses.  This event boosted my faith in outbound monitoring and 
destroyed my faith in AV products.

George Toft
