If this default is unchecked, NAV will immediately scan the files when theyвЂ™re uncompressed, so your Mac maintains its level of security. NAV actually decompresses and then recompresses files on the fly, which makes such scans slightly more resource intensive.

The application automatically scans all attached volumes, as noted above, and it also scans compressed files (.sit. Statistics let you see at a glance what the program has done.Speaking of default settings, NAVвЂ™s defaults are a bit aggressive. Norton AntiVirusвЂ™s new user interface is straightforward and easy to use. Once a file lands in NAVвЂ™s quarantine, a few things can happen: NAV can attempt to repair the file and remove it if possible you can delete the file or, if it was flagged erroneously, you can restore it to its original location. If it canвЂ™t repair the virus, it whisks that virus into Quarantine, a special folder on your hard drive, where it canвЂ™t harm your data. NAV will repair any viruses it finds and alert you that it has done so. When NAV finds a virus (and it found all the test viruses on my system), an alert window appears in the lower left corner of your screen. The Auto-Protect function constantly runs in the background, making sure that your MacвЂ™s defenses are not breached.
