AVAST Software Taps Mailshell To Protect Its Users From Spam And Phishing

PRAGUE, CZECH REPUBLIC, October 18, 2010 - AVAST Software has signed a new contract with Mailshell, the leading provider of traffic reputation, anti-spam and anti-phishing engines for OEMs, confirming the continued integration of its email filtering technology into the premium avast! Internet Security Suite. Over 130 million users in more than 240 countries worldwide are protected from malware by avast! antivirus products.

The current version of avast! Internet Security includes the combined protection of the Mailshell Anti-Spam engine with Mailshell LiveFeed, a real-time data service that quantifies traffic reputation via advanced statistical models. Unlike other reputation services that provide only a binary 'good' or 'bad' rating, LiveFeed provides granular trust ratings with automated adjustment over time as reputations change. By focusing reputation on mathematical models, rather than simply an 'IP black list' approach, LiveFeed provides more accurate, highly scalable detection.

"Mailshell's technology provides a great balance of low memory usage, high throughput and consistent accuracy," said Vincent Steckler, CEO of AVAST Software. "This partnership provides our users with best-of-breed protection while allowing our development team to focus on the other core technologies that make avast! unique."

"avast! is now among the most popular and widely used security products in the world," said Tonny Yu, CEO of Mailshell. "We're thrilled to help the AVAST team provide even more value to its massive global user base."

Mailshell's SDKs, including LiveFeed, provide complete and consistently accurate protection against email fraud, phishing and spam. The SDKs are available on more than 10 operating systems and require as little as 32KB of code on the device. Mailshell's SDKs are embedded into security, networking and messaging products including software appliances, SaaS platforms, gateway security software, desktop security suites, UTM, mobile devices, wireless access points, firewalls, modems, and other low memory devices.
