This article provides information on identity files.
First seen in Sophos Endpoint Security and Control
IDE files contain threat identities which allow Sophos Anti-Virus to detect and disinfect the latest malicious software and other threats.
Sophos Anti-Virus IDE files are cross-platform. All operating system versions of Sophos Anti-Virus can use the same IDE files.
After one month the current IDE files are rolled up into the virus engine to speed up scanning times.
Therefore Sophos recommends that you upgrade Sophos Anti-Virus whenever there is a new engine released - currently this is monthly.
In any given period, Sophos will have analyzed many hundreds of new viruses and other threats. Some of these will probably require updates to the scanning technology, often because there are changes in the kind of objects that viruses can infect, e.g., new Microsoft Office file formats.
For this reason, Sophos can only offer technical support to customers who are using an up-to-date version of Sophos Anti-Virus.
