I have slected to do a fast scan when a flash drive is inserted (in settings). The fast scan settings have been set to the default, i.e. memory, start items and boot sectors. However, when I insert a flash drive, looks like Kaspersky is doing to full drive scan, which are taking very long time. I didn't have the patient to wait until it finishes. How can I let Kaspersky to scan the flash drive very quickly?
