Just done a security check with Symantec Online, and also Sygate (which is my firewall)
Sygate reports everything closed and no problems, but Symantec reports this :-
Can anyone explain why the difference, and if there is a risk, how to configure Sygate to close it.ICMP Ping Ping. Ping is a network troubleshooting utility. It asks your computer to acknowledge its existence. If your computer responds positively to a ping, hackers are more likely to target your computer. PORT OPEN......Solution - Get a firewall!!
