Of 2400 legitimate emails, BitDefender returns only one false positive

BitDefender�, an award-winning provider of innovative anti-malware security solutions, today announced that BitDefender Security for Mail Servers 3.0.2 has achieved its sixth VBSpam Award in a row, in the latest Virus Bulletin Anti-Spam Comparative Review. Designed for Linux servers, Security for Mail Servers 3.0.2 achieved Gold for its low false positive rate coupled with its high spam catch rate.

Linux products were tested on a SuSE Linux Enterprise Server 11 for a period of 20 days. The email corpus consisted of all emails sent to several Virus Bulletin email addresses, mixed with a spam stream provided by Project Honey Pot. Emails from both sources were sent through the products in real-time. Additionally, the test messages were in multiple language and character sets, including English, French, Asian languages, Russian, Dutch, Norwegian and others.

BitDefender Security for Mail Servers 3.0.2 caught 97.84% of the spam messages in the test, with a false positive rate of only 0.04%.

�We are thrilled to receive another VBSpam Award for BitDefender Security for Mail Servers 3.0.2,� said Catalin Cosoi, BitDefender Senior Researcher. �This award represents our sixth consecutive honor from Virus Bulletin, and we are particularly happy with test results showing only a single false positive out of 2400 genuine emails.�

For the past five months, BitDefender Security for Mail Servers 3.0.2 has successfully used a new technology based on live query. Stemming from the cloud-computing paradigm, this technology provides an immediate response time and protection to users all over the world, regardless of language or what type of spam they receive. With this technology, when a new email arrives, it is first scanned locally with proprietary, proactive antispam solutions. If it passes the initial filtering sequence and still cannot be categorized as spam or legit, a proprietary algorithm extracts key elements from the analyzed mail and creates something similar to a unique encrypted fingerprint of that message. If the BitDefender network of servers finds a match in its databases of known spam fingerprints, it issues a block command to the client application.
