With NOD32 v4.0,437, on my Win2kSp4 computer, the NOD32 system tray icon menu includes (among other things) the following two options: Disable real-time file system protection Disable Antivirus and antispyware protection If I disable either one, and then look again at the NOD32 system tray icon menu, both Disable options have become Enable options, suggesting that both have been disabled even though only one was selected to be disabled. Is that a bug, or is there a rationale for tying both together? If that's not a bug, apparently NOD32 needs me to disable not only file system protection but also antivirus and antispyware protection (and vice versa). If so, I don't understand why the icon menu contains two separate Disabling options. Roger Folsom ________________________________________________________________ BACKGROUND This issue has arisen because installations of new software usually recommend disabling or exiting any currently running programs. When I install new software, of course I am in the Administrator account. And almost always I have previously downloaded and saved the software. (Adobe Reader no longer lets me do that, which was one of several reasons for my switch to Foxit Reader.) To comply with the usual "shut down or exit everything else" installation recommendation, before installing the software, I shutdown my internet connection (unless the installation requires internet access) and then use NOD32's system tray icon to disable file system protection, because I am guessing that file system protection is what would cause conflicts.
