I have W7 64 bit, Free Avira anti virus, Malawarebytes and Spywareblaster. Waiting for SAS to issue 64 bit version. When I run Avira, it reports no viruses , no warnings. It does mention 5 "Hidden Objects". Malawarebytes shows no warnings. When I had SAS it somtimes found a few items that were missed by MAB - these were Google and MS things which seemed harmless. Do I let sleeping dogs lie, or is there some safe way of seeing what these hidden objects are?
