I have just ran a full system scan which I do often. It identified Winzip18.0 as containing "Infostealer" and it was quarantined. After spending about one hour with a Norton Rep he finally said it was a false positive. Has the sensitivity for finding instances of infostealer changed? I do not use Winzip18.0 and have not since I originally downloaded/purchased it in November 2013! I haven't used it in some time, but I do use Winzip9.0. Has anyone else experienced a false positive in Winzip18.0 in a backup file?
