Abstract
An individualized time-to-live (TTL) is determined for a reputation score of a computer file. The TTL is determined based on the reputation score and the confidence in the reputation score. The confidence can be determined based on attributes such as the reputation score, an age of the file, and a prevalence of the file. The reputation score is used to determine whether the file is malicious during a validity period defined by the TTL, and discarded thereafter.
