Symantec Endpoint Recovery Tool – ISO-boot disk image based on Win PE, with which you can scan the computer without booting the OS and antivirus databases can be downloaded from the Internet or any medium. There is information about the program at home and powerful, it is painted in detail how to add a fresh base for the antivirus.

As for the discrepancies versions of the ISO file itself and Recovery Tools, I can only assume that the numbering of the image is tied to the version of Windows PE.

The Symantec Endpoint Recovery Tool (SERT) is a bootable CD that can scan and remove malware from an infected computer. SERT is useful in situations where computers are too heavily infected for the Symantec Endpoint Protection client installed upon them to clean effectively. It is also necessary against specific threats which have the ability to completely hide from Windows, or that have techniques that manipulate Windows into protecting the malicious process against Symantec Endpoint Protection’s scanning and remediation components.
