  13. Select the Schedule tab. This section defines how often your computer runs a scan for infected files and how often it checks for updates. Select the following options:
    • For the Scan option, select a day and time of at least once a week. You may want to set a time when you will be logged into the computer but aren't actually using it because a scan will use processor cycles and could slow down your computer.
    • For the Update option, select a day and time for the program to go to the internet and check for updates. It is strongly suggested that you check for updates daily.
  14. Select the Folder Sentry tab. Folder Sentry actively scans folders as their contents change, whereas the scheduled scans only at the scheduled time. Select the following options:
    • Drag folders to be watched into the preferences. Do not watch the directory where you keep virtual machine images because scanning them can take some time and they are constantly being modified.
    • Scan inserted disks. Note: Do not set this option if you connect to network drives.
    • Launch ClamXav Sentry when you log in to this computer.
    • Quarantine infected files.
