VirusScan 8.0

Automate Scanning with VirusScan 8.0

The standard settings for VirusScan will automatically scan:

• Floppy disks on access and at shutdown
• The boot sector and the startup files at startup
• Program files and documents (including Word documents and Excel spreadsheets) when they are accessed.

You may change these settings at any time by double-clicking on the VShield icon in the lower right corner of your screen (near the clock), and then clicking Properties.

To scan your entire hard drive for viruses:

1. Double-click on My Computer (in Windows XP, from the Start menu, choose My Computer).In the My Computer window, right-click on the icon for your hard drive (usually C: or Local Disk). From the menu that appears, choose Scan for Viruses.

The VirusScan window will expand to include information about any viruses which are detected.

For more information about scanning, see VirusScan's Help menu.

You can configure the VirusScan Console to scan your hard drive on a regular basis. We recommend that you schedule a weekly scan of all files on your hard drive, especially if you have configured AutoUpgrade to download SuperDATs automatically.

NOTE: When VirusScan automatically scans your computer, the scanning window does not appear, unlike the scanning window for VirusScan 4.5.1. To check if it is scanning, right-click on the VShield icon and next to the Scan All Disks tasks it should say Running.

Make sure to choose a day and time when your computer will be left on but will not be heavily used (e.g., lunch time or a regularly scheduled meeting time). If you use AutoUpgrade, it is best to schedule the scan to take place one and one-half hours after you have scheduled AutoUpgrade to run.
