1. A method comprising: determining that a plurality of objects is not infected by malware; selecting a value of an update identifier in an update log that is associated with the plurality of objects to be a reference value in response to determining that the plurality of objects is not infected by malware, the update identifier indicating a number of updates that occur with respect to the plurality of objects; incrementing the value of the update identifier for each update that occurs with respect to an object of the plurality of objects to provide a respective incremented value; determining that access to a designated object that is included in the plurality of objects is initiated; determining whether the incremented value that is associated with the designated object is greater than the reference value; and allowing operations to be executed with respect to the designated object in absence of scanning the designated object for infection by malware in response to determining that the incremental value that is associated with the designated object is not greater than the reference value.
