If you have downloaded Sophos Anti-Virus for Mac Home Edition version 9 from a location other than Sophos you should confirm that it is genuine by matching the checksum of the file you have with the checksum we publish. You may also want to checksum the file you have downloaded from sophos.com to ensure 100% of the file has been transferred to you computer and saved correctly.
The instructions below guide you through how to generate a checksum for your Sophos download using the correct type of checksum.
What is a checksum?
Each version of a file has a unique checksum. This can be used to determine the authenticity of the file and ensure no part of a large file has been lost during the download process. There are different checksum methods (common ones are MD5 and SHA). We publish the check for the Mac Home Edition as a SHA 256 checksum.
