In the past day or so, which is within a week of a pushed upgrade to Norton 360 that gave it a new look (showing version 22.5.10.124) I've been getting "Risks in compressed file" notifications, with many of them pointing at .cab files for QuickBooks, printer drivers, and Act!...
Are these likely to be real threats? The suggested solution is to delete (quarantine?) the files... I would do that, but doing so seems likely to 'break' the program that owns the .cab file, something I can't really afford.
