To provide your e-mail users with anti-virus protection, you can use either the Dr. Web or Kaspersky Antivirus solutions. Both Dr. Web and Kaspersky Antivirus can scan server's mail traffic in real time, however, only Kaspersky Antivirus allows fine tuning and filtering of specific file types from attachments.
The both programs require an additional license key with annual renewal. Check the current prices with your provider or visit Parallels site at http://www.parallels.com/en/buyonline/plesk8/.
To install Dr. Web or Kaspersky Antivirus:
After the installation is completed, obtain and install a license key for the selected antivirus program, as described in the following steps.
If you installed Dr.Web, you can switch on antivirus protection only on a per-mailbox basis, and only after you have set up mailboxes. By default, virus definitions are retrieved every 5 hours from Dr.Web site, and this setting is not changeable through the control panel.
To set up anti-virus protection for a mailbox, proceed to the Protecting Mailboxes From Viruses section.
If you installed Kaspersky Antivirus, for instruction on setting up and using antivirus, see the Kaspersky Antivirus Module Administrator's Guide at http://www.parallels.com/en/products/plesk/docs/.
