What IS 'malware'? If it doesn't affect your computer in any way, if it doesn't slow you down, cause any symptom whatsoever, how is it malware?
Burying your head in the sand, at least to me, implies ignoring a potential solution to your problems. If you haven't GOT any problems, never have HAD any problems, and keep your ear to the ground for any substantiated change in the whole affair (not rumor mill topics ground out primarily by the security industry), I say bring it on! I have a good backup regimen (might not have security problems, but hard drives fail, sooner or later!), and am prepared to wait for real life problems to occur.
Like I said, (to paraphrase)... 15+ years with my head stuck in the sand, not a grain up my nose. Put your PC out on the web for a DAY without security software, then come back and tell me who has the problem...!
