Easy: open the configuration window and select the Updates tab, where "Update using an Internet connection" and "Source URL: www.antivir.de" should already be entered as default settings. If you use a proxy server in your company, you should also enter the data for this. Now confirm with OK, open the Scheduler and add a new job. Select "Update virus patterns through Internet or Intranet" and an appropriate interval, e.g. every 300 monutes, this every 6 hours. Once you have completed your input, AntiVir is ready configured, and will now search for new signatures in the internet every 6 hours. The new files will be installed automatically without the need to restart the AntiVir service.
