The company, which also has TV broadcasting, advertising, publishing and ISP (IOL) divisions, selected Central Command's Vexira Antivirus for Linux after stress testing the AV offering to determine whether it was capable of dealing with its high-volume commercial email systems.
Lourenco de Almeida, director for e-mail and online services, Media Capital Group, said that the antivirus system had to be scalable enough to deal with "millions of email messages a day".
"We vigorously stress tested Vexira Antivirus on our production email servers and the Vexira technical support system for over 2 months prior to purchase. We found that it is simply the best Linux antivirus product on the market with outstanding technical support that is responsive and understands the nature of large-scale email systems," de Almeida said.
"Being the largest email provider and web portal operator in Portugal, our reputation is at stake and we are very aware of the competition facing us."
Vexira Antivirus for Linux is designed for Linux x86 (IA32) platforms including Redhat, Red Flag, SuSE, Debian, Gentoo, Mandrake and Slackware. It supports email applications including Sendmail, Postfix, Qmail and Exim.
