1. An apparatus comprising: at least one processor; and at least one non-transitory memory storing instructions that when executed by the at least one processor, cause the apparatus to:
select one or more tasks determined to be performed by a user device before a next charging of the user device,
wherein the one or more tasks to be performed by the user device are selected at least based on a predicted use of applications on the user device as determined based on a past use of applications on the user device since the user device was last checked for malware;
enable a power trace to be obtained wherein the power trace provides an indication of the power consumed by the user device while the one or more tasks are being performed; and
enable the power trace to be analysed to provide an indication of the presence of malware,
wherein analysing the power trace comprises comparing the obtained power trace to stored power trace data obtained from a plurality of other user devices.
