Threat Scores and What to Do

Threat scores play a vital role in assessing the potential maliciousness of files, offering a numerical representation based on file analysis. In the context of Malcore Office Shield, these scores are color-coded to enhance interpretation of the score. The color-coded system is as follows:

  1. Green: Files marked in green indicate a very low likelihood of being harmful, with a score ranging from 0 to 10%. Users can most likely consider these files safe for use.

  2. Yellow: Files with yellow markings possess suspicious indicators, and should be handled with caution. These files fall in the score range of 20 to 40%, and should be handled with care.

  3. Orange: An orange label indicates files with multiple suspicious indicators, that presents a higher risk. Users are advised to remove such files from their systems, as they have scores between 40 and 60%.

  4. Red: Files flagged with the red label require immediate action. With a threat score of 60 to 100%, these files may pose a significant risk to users and should be removed from the system to prevent potential harm.

By providing these easily identifiable color-coded indicators, Malcore Office Shield empowers users to make informed decisions based on facts. This system enables users to visually see the safety of their files, providing a more secure and productive computing environment.
