Hey , I'm still getting "viruses" just by "being online" and not surfing the internet. I have High Speed Cable Modem, which is always ON. Norton Antivirus is active and my Norton Personal Firewall is always enabled at start-up. BOTH products are up-to-date, and Window's XP is up-to-date, aswell. I went on vacation and left my PC (computer) ON the entire Christmas week. NO internet browser was open. NO programs running at all, "except my firewall and NAV". When I get back from vacation I now have several viruses, just by leaving my PC on. I have as I mention Norton Antivirus auto enable at sartup. Norton Personal Firewall auto enabled. Microsoft AntiSpyware auto enabled and up-to-date. All that and still get viruses. I have tried all other programs and NONE have prevented viruses from getting "into" my computer. I was looking at the settings in my Norton Personal Firewall 2004, and there is an option to BLOCK or PERMIT Fragmented IP Packet Handling. This is how it's written: Fragmented IP Packet Handling O Permit all except suspected attacks (recommended) O Block all It was set to "permit all" but I switched it to "block all" to see if that helps to prevent viruses. What does this feature mean or do? how should I have it set? After setting it to "block all", I went to http://scan.sygate.com/prestealthscan.html and the "test" came back all "blocked". Before when I had it set to "permit all" Port 80 and another port came back open, now it show's all BLOCKED. Is this Good Thanks Everyone!
