Is there a reliable comparative test showing how efficient different AVs are at cleaning problems that they find. There's lots of research on how good they are finding bad stuff... but then what? Some seem to leave you in the lurch some do not. But which? Checked av-comparatives.org but cannot see anything there. At westcoastlabs.com they say passed or not and checkvir.com says sample disinfected but I haven't seen much that reaally answers the question.
