GMS AV offers server based integrated Anti-Virus scanning on all incoming and outgoing emails, including content, headers and attachments. GMS Anti-Virus has automatic updates to ensure it is always scanning up to date viruses. It will check for signatures files every 15 minutes. If you use the Proxy server built in to GMS, AV will also scan web pages. GMS Anti-Virus was one of the first AV solutions to include Heuristics and also includes disinfection to ensure end users still receive important and safe email.
