Antivirus and Security Software from Sophos

Psst, Mac user! We have a free Mac anti-virus just for you.

Download latest virus identity (IDE) files

If you are running an older version of Sophos Anti-Virus and do not automatically update your protection, you should download virus identity files (IDEs), which provide detection and disinfection of viruses, worms, Trojans and spyware.

All the IDEs you need are available in a single compressed file. The file is available in two formats: a Zip file or a self-extracting file. Files are updated every time we release protection for a new virus. (To use IDE files, you must know which version of Sophos Anti-Virus you are running and how to use virus identity (IDE) files.)

Our self-extracting files are not compatible with Windows 2003 and Windows Vista. Please update the IDEs automatically or download the Zip file.

Please note: We do not provide IDEs for versions of Sophos Anti-Virus that are more than three months old.
