Recurrent Pattern Detection (RPD™) Technology

  • Recurrent Pattern Detection (RPD) uses patented technology to identify patterns which are content agnostic to safeguard the original message. These patterns cannot be used to reconstruct the original message.
  • RPD extracts and then analyzes relevant patterns, which are used to identify massive email-borne outbreaks. It classifies both distribution and structural patterns within an email message.
  • RPD patterns are compared to the local cache which provides fast match results for more than 70% of the patterns. If a pattern is not in the local cache, RPD will query global data centers for a match to provide true real-time protection...
  • RPD is designed to distinguish between the distribution patterns of solicited bulk emails, representing legitimate business correspondence, from those of unsolicited bulk emails, representing spam.
  • RPD identifies incoming threat messages with very few, if any false positives. Not only are the patterns content agnostic, they are also language-independent making it equally effective for all message formats and encoding types.

Frequently Asked Questions

Eicar is a tool designed to determine if an antivirus product is installed properly. This is a small .COM file used to test the effectiveness and operability of on-access and/or on-demand scanning of an antivirus product.It consists entirely of printable ASCII characters, so that it can easily be created with a regular text editor. Any anti-virus product which supports the Eicar test file should 'detect' it in any file which starts with the following 68 characters:X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*You can create your own test file by copying the text above into NOTEPAD and saving the file as EICAR.COM.

This article describes running a third-party AntiVirus solution on the same machine as MDaemon AntiVirus.It is possible to run two Antivirus programs on the MDaemon machine. An Antivirus program that runs in the background and checks all files - not just emails - would not be a bad idea!To ensure that there is no compatibility problems or clashing between MDAV and your other antivirus solution, we recommend that you exclude the entire MDaemon directory structure from any real time scanning.
