Klaus, You sound up to date on computer protection. Included in Norton's System Works is firewall protection for back door Trojan attacks. I like you have my address all over the place. In my business, my Email address happens to be all over the world.(probably most of us are, another interesting situation for another day). My understanding is there are "basically" viruses, worms and Trojan horses. Viruses, worms enter in the "front door" of your computer using your Internet Service Provider(ISP), maybe DSL or Dish or whatever other delivery system you use for data bits. Trojan horses access your computer through the "back door" i.e., (1) an open port, (2) a configured port not currently hooked up to any peripheral, (3) an unused port, or the one your regularly use to access the internet. If any of these ports "blinks" and lets the Trojan horse access you machine, I within four hours I could easily find out everything on your hard drive, or more sinister and evil permanently damage the hard drive. Unfortunately, not everyone on line are ethical, honest, family members like us. Scary. At my knowledge level, I can probably handle any attack that comes down the wire.(Please, God, forgive me if I sound arrogant, that is not my intention). I say this because for the Average Joe and Jane computer user, lacking the chance to build computers as I do, don't try homemade fixes. The people that write these heinous programs are Evil, they goal is to cause angst and fear in us. Understanding this issue is our hole card and our safety. The people at McAfee and others are working 24/7 to successfully thwart these criminals. Get coverage for all three of these threats. I am sure MacAfee has similar products. Several years ago, I had bad luck with their products and am now attenuated to Norton. I suspect a backdoor system seven Trojan horse has gotten into the web site that lists the California Petition Signature record of names. Urban terrorism. Any thoughts? Gary
