Hi there. I noticed my G4 iMac running a little slow the other day - plus expolrer and safari were both acting odd - not loading 40% of sites. This could be a fault with my ISP of course but I started checking about. "I'm now running Snort/HenWen/Letterstick and keep getting this: A new alert has been issued... The alert contents: "ICMP PING Cyberkit 2.2 Windows" The alert was triggered by an ICMP packet Source..." etc I'm getting hit by this every 5 seconds - non-stop. Any clues anyone?
