Safe habits are a must - this I can agree with very easily. Just that I don't have to worry so much when the next bit of crap comes down the pike (for instance, did you know that PDF files are currently a malware carrier if you use a not-currently patched version of Adobe Reader to open it?) That said, all the care in the world won't save you from a hijacked website with an IFRAME embedded in it, if your A/V doesn't know about the malware yet and has a signature for it. Now if you're really paranoid, you could always do one thing... build/buy a really beefy computer, then install VMWare Server on it (it's a free download - ESX and Virtual Infrastructure are the pricey bastiches). Build a virtual machine on it and have a ready clone of it saved off somewhere. If your main VM gets bitten, you can always delete it and copy off the clone for the restore. /P
