EchoTrail Prevalence Score (EPS)
The EchoTrail Prevalence Score (EPS) is calculated using a formula that takes into account much of the process metadata we collect from computers in the wild. The score is a number between 0 and 100, with a higher number indicating a higher incidence of this process being run in the wild. A low score would indicate an unusual or new process that hasn't been seen often.
