nothing is 100% really.... there are new nasties written all the time to bypass security programs and sometimes the security program people are just catching up how to get rid of them. Some programs protect against one new nasty sooner, then later it might be another company that catches the newest one.
You can do a google search for independent antivirus and firewall tests and reveiws where they compare several at a time. I'm looking at a new antivirus NOD32 as a possibility, it got good ratings and a friend of mine recommended it, although I haven't tryed it yet. I think Avast is good, it takes a little while to figure out the interface, but it's worth the effort. I like Zone Alarm as a firewall, but I'm not sure about their antivirus... Personally I like Avast much better than Norton.
Antispyware, you can have several on your computer and just set most of them so they;re not running all the time or updating automatically. Then you can just use them manually once in while to scan and clean stuff out if you have problems or whatever.
