How To Update Your Virus Scan

McAfee VirusScan

New viruses are created and distributed every day. Virus protection software such as McAfee VirusScan, works with virus definition files to detect and remove viruses. To be effective, the virus definitions must be updated frequently. McAfee VirusScan uses a facility called AutoUpdate to download and install virus definition files directly over the internet.

To Schedule Automatic Virus Definition Updates

  • Start McAfee VirusScan by double-clicking on the McAfee Console icon in the system tray. The icon looks like a magnifying glass with a small clock on the upper right hand side located in the system tray, i.e. the group of small icons located by default in the bottom right-hand corner of the screen.
  • Double-click "AutoUpdate".
  • Click on the tab called "Schedule".
  • Click the check box beside "Enable".
  • Select "Weekly" as the frequency, and then select a random day and time.
  • Choose a time your computer is likely to be on.

Norton AntiVirus

New viruses are created and distributed every day. Virus protection software such as Norton Anti Virus, works with virus definition files to detect and remove viruses. To be effective, the virus definitions must be updated frequently. Norton AntiVirus uses a facility called LiveUpdate to download and install virus definition files directly over the internet.

You can update your virus definitions on demand or schedule your system to retrieve updates automatically at specific times. By default Norton AntiVirus updates its virus definitions on the first system restart after being installed. After that, the virus definitions are updated every Friday at 8 p.m. If your computer is not on at that time, it will update when you turn the computer on.
