I've noticed the same thing with Cisco PIX site-to-site VPN tunnels.

Hi,

i don't know if this is the right place to report this:

The online update function of Avast Antivirus (www.avast.com) generates
false positives on SID 469. It seems to use a ICMP ping message with
data
size 0 to check if www.avast.com can be reached.
