FOR IMMEDIATE RELEASE
Xtrawise Anti-Spam Filter Offers Firewall Level Protection Against Spam
Oakham, Rutland (PRWEB) November 5 2003 – Xtrawise.com today announced Xtrawise Anti-Spam Filter for Microsoft Windows, a desktop email filter for consumers and businesses offering extensive protection against the growing menace of Spam and malicious email attachments.
Xtrawise Anti-Spam Filter offers unprecedented ease-of-use by automatically intercepting email once installed without any complex email client configuration requirement or need to change the way email is collected. Bayesian filtering determines the probability that incoming email is Spam by examining every part of the message. If the indicators are negative the message is delivered to the email client as usual. Otherwise the message can be either silently deleted – with the ‘From’ address stored in the activity log – or quarantined to a hard disk folder for automatic deletion after a specified number of days, thus allowing the user time to review messages pending deletion. Each time an email is sent or received the probability database is updated to improve future filtering performance.
Xtrawise Anti-Spam Filter includes safeguards to reduce the occurrence of ‘false positives’ – wanted email erroneously classified as Spam. Subject passphrases – similar to passwords but usually including multiple words – can be defined. When these are detected in the ‘Subject’ field of incoming email the messages are instantly delivered to the email client without further filtering. Blocked and trusted sender email addresses – or even entire domains – can be defined resulting in automatic delivery or deletion of messages. The user can opt to accept incoming mail from trusted senders only. Xtrawise Anti-Spam Filter can automatically reply to emails from non-trusted senders on the user’s behalf, adding a question that can only be answered by a person and when that person correctly replies the email is delivered. Spam is mostly automatically generated and so a response to the challenge will likely never be received.
Xtrawise Anti-Spam Filter protects the user from malicious email attachments. Before attachments are delivered to the email client any executable windows filetypes are harmlessly renamed – with the original filename recorded in the activity log – providing protection against accidental or impulse opening of malicious email attachments. In addition, HTML tags that are able to launch executable files or record the successful opening of Spam messages can be safely removed from incoming mail. If a Trojan, Virus or Worm compromises the user’s computer, Xtrawise Anti-Spam Filter provides a visual indication whenever applications begin broadcasting to the Internet by email, HTTP or Internet Relay Chat by displaying a flashing icon. An outbound email lock can be instantly engaged to prevent a Virus or Worm from spreading further.
Xtrawise Anti-Spam Filter blocks Windows Messenger Service popup windows by default. The Windows Messenger Service is increasingly being abused by Spammers to deliver unsolicited advertisements to computers running Windows 2000 and Windows XP.
The partnership of adaptive Bayesian filtering and safeguard options such as challenge/response authentication and subject passphrases dramatically reduce the occurrence of ‘false positives’, an issue which has until now proved to be the major failing of Anti-Spam products. Xtrawise Anti-Spam Filter enables the user to eliminate junk email without fear of missing important correspondence.
