I downloaded a zipped file with an .exe in it for a program distributed from a commercial product website that I believe is safe. When trying to extract the file from the .zip, the .exe never makes it--it's always deleted under the threat name Suspicious.MH690 (which I've read elsewhere in another thread is a recent addition to NAV definitions).
I have to turn NAV off to get it to execute. I then have to exclude the file in Exclusions to get it to stay on the hard drive--otherwise, as soon as I turn NAV back on, it's gone.
I tried just scanning the file by itself after it was unzipped and excluded just to see if it detected any other threat after being successfully unzipped, and NAV deleted it with the same message: Suspicious.MH690.
I'm pretty comfortable this file is safe. I think just excluding the file from NAV is the way to go here, but is there a way to tell NAV not to delete it for Suspicious.MH690 but to look for other threats within the file? Is there a better way to get NAV to let the file unzip without turning NAV off for a few moments?
