Are Portable Apps virus?

From personal experience with Norton Antivirus 2005, I have come to the conclusion that it, and all of the other versions before it, are EDJ programs (Expensive Deffective Junk). When you have a high speed connection, like cable or DSL, Norton let's just about everything in. The only time it offers any protection is when paired with another antivirus program. I find that Norton and AVG Free work pretty well together, but don't use both of their fluffed up add-on products (like AVG + Firewall, or the infamous Norton Security Suite) You should never trust any of those all-in-one suites. Instead, you should have a custom system made of programs from a variety of companies. For example, use Zone Alarm Firewall, Nod32, AVG Free, Ad AwareSE Personal, Spybot S&D, and CCleaner. If you know what to look for, Zone Alarm is a good permissions based firewall. It let's you know if any program does anything suspicous, such as Explorer.exe (file browser in Windows) trying to connect to the net, which is a clear sign that your computer is infected because your file browser has no reason to connect to the net.
Ad Aware, Spybot, and CCleaner are the ultimate spyware, adware, and cookie crunching trio. CCleaner also doubles as a cool system utility. Nod32 is pretty cool and it doesn't conflict with AVG Free. I have heard that it does however conflict with Norton to the extent of automatic updates. If you set Norton and Nod32 to manual scan, and just use AVG's auto scan (scans incoming downloads and stuff), which is enabled by default, it should work just fine. Also, you should only scan your system with one program at a time. If you try running two or more scans at once, World War 3 will happen on your computer. I have one last very important tip to all of you who use cable or DSL. Always connect through a router, even if you only have one computer. Most routers hide your real IP address, so port scanners wind up attacking the router instead of your computer. Most cable modems come with an ethernet port. Use one network cable to connect the modem to the router, and another cable to connect the router to your computer. It also cuts down on Denial Of Service attacks and helps to prevent you from being booted out of chat rooms. Note: This method may not be compatible with some ISPs and it can take longer then usual (about 1 hour) to connect for the first time using this method.
