Hi bob3160,
I have the strong impression that this is not necessary, and if you get infected it means a. your practices were insecure, b. your luck was out big time.
If you have adequate updated fully patched software, taken measures to reduce the risk of infections, like broad theater scanning solutions for av-af-as-ark, together with a normal user account, a NoScript solution on FF or symantec's NoScript in IE, and you have the security experience to stay away from where malware infestors may hide or made yourself invulnerable to them, you need not be infested with malware in the broadest sense of the word (no tracking cookies even), use hjt crap cleaning and other knowledgeable means. I am proof of it since I became more involved in malware cleansing and knew more ways to protect myself "from visiting this forum frequently" I had 0 malware on my box, two FP's but that could be taken into account,
and this for several years where malware numbers doubled every year,
