You do realize any "real time monitoring" AV is going to do that since any
AV worth it's salt will scan opening files on startup and closing files on
shutdown to catch stealth/polymorphic viruses. In both your posts you seem
to imply running Avast is not good just because Vista flags them as
"slowdowns" which I find a tad irresponsible. The performance hit is minor
to say the least (oh the noes, if i dump avast my shutdown time is 3 seconds
faster... what a resource pig!).
