The main features: The Novell Server is fully protected! RAV offers protection both in on access mode and on demand mode. Full control of the actions to be taken when a threat is discovered: clean the virus, deny access to the file, rename, delete, or copy the file to Quarantine directory. The scanning process is performed when opening or closing a file, thus detecting when the Novell client may infect the files from the server. RAV AntiVirus notifies the user of the Novell client when a malware was detected. Also, it can optionally send the same notice to the server console. Novell GroupWise - both incoming and outgoing e-mail flow is scanned and filtered. Once the Novell GroupWise is configured to route all the e-mail to the secondary SMTP services directory, RAV Antivirus scans the mail files from that folder. The clean e-mail files are moved to the default SMTP directory in order to let Novell GroupWise to deliver it. If an e-mail contains an infected or a suspicious object then that object is moved to the quarantine directory and replaced with a text file which contains the following message: "RAV AntiVirus has deleted this file because it contained dangerous code".
