Updating The Virus Database

It is important to have an up to date Virus Database since new viruses are often discovered and reported on a daily basis.

The files in the Virus Database directory contain information on virus patterns. Updated versions of these Virus Database files can be obtained from a number of sources.

If you obtained the Virus Database files and have them locally then you can simply copy them to the Virus Database directory. Otherwise it is recommended that you update the Virus Database from the Internet.

Updating From The Internet

To update the Virus Database from the Internet you need to have the virus database update program called freshclam (part of the Clam Antivirus package), and have it set up as follows:

  1. su
  2. (enter password)
  3. chmod +s /usr/bin/freshclam
  4. chown clamav.clamav /usr/bin/freshclam
  5. chown -R clamav.clamav /usr/share/clamav
  6. exit

If the above operations were performed successfully then at this point you can run AVScan as any user to update the Virus Database from the Internet.

To update the Virus Database from the Internet, click on the Update button. AVScan will automatically call freshclam to update the Virus Database from the Internet and its progress will be displayed on the Status Bar.
