As you know, McAfee recently had a serious error with a DAT file that mis-identified good files as viruses. Depending on your settings, if your server did an on-demand scan when that DAT file was active, you may have either quarantined or deleted important files. These lost files may not become apparent to you until your server next reboots, which may be when patches are next applied. In some cases, we have been able to tell that you've lost files and have already notified you, if you have not heard from *** Support, and you are running McAfee Virus Scan, we strongly recommend you review the on-demand scan logs of your McAfee to ensure that you restore any quarantined or deleted files before you reboot your system.
