I tested Norton Internet Security 2012. I tested 2 ways i.e already downloaded malware in a folder & downloading malware through web using internet explorer. When I download & run or save malware through Internet Explorer, NIS analyzes the files & gives verdict i.e the small analyzing window in the right hand corner. But when I run the already locally saved malware in a folder, NIS doesn't analyzes them, this is by design or some prob here? I thought download protection sonar was for web & file insight was for both web & local files but it doesn't seems so. That means sonar & file insight are for web only & not local files i.e file insight too is for web only, right?
