Abstract
A computing device determines, for a first time period, a usage-based file list identifying one or more executable files. The computing device determines, for each of the one or more executable files identified by the usage-based file list, whether to perform a malware scan upon the executable file based on a cached record for the executable file. The computing device schedules, for execution during a preceding time period before the first time period, a malware scan for at least one of the one or more executable files based on the corresponding determination of whether to perform a malware scan. Each scheduled malware scan is initiated as a low priority thread for execution. The computing device performs each scheduled malware scan during the preceding time period.
