VSAPI 2. 0 Virus Scanning API 2. 0 (VSAPI 2. 0 as provided in MS Exchange 2000 Server) does not allow the deletion of infected e-mail files. Since the virus infected e-mail message attachment cannot be deleted, its filename is changed: AVG for Exchange 2000/2003 Server appends the . virusinfo. txt extension to the original filename. The file content is overwritten with a message about the known virus. If a virus is found directly in the message, the whole body of the message is overwritten with a note saying a virus was found inside this message. Virus Scanning API 2. 5 (VSAPI 2. 5 as provided in MS Exchange 2003 Server) also allows deletion of infected messages. This feature can be set up in AVG for MS Exchange 2000/2003 Server configuration dialog. 6. 1. 3.
