METHOD FOR SELECTIVE REPEATED ANTIVIRUS SCANNING OF FILES ON MOBILE DEVICE Russian patent published in 2020 - IPC G06F21/56 G06F21/64 

FIELD: physics.

SUBSTANCE: invention relates to the computer equipment. Disclosed is a method of partial resetting results of previous antivirus scanning of files, implemented using a mobile device, according to which a local database for files is stored, where each entry is added to the database when the corresponding file is considered not malicious as a result of the antivirus check, and contains information identifying the file, and information on performed antivirus checking, which includes at least date of antivirus scanning of file; setting the records reset threshold; after updating the antivirus databases, estimating the probability of resetting the results of the previous antivirus check for each record from the database; wherein evaluation of the value is higher, as more time has elapsed from the specified date of antivirus checking of the corresponding file and more updates of antivirus databases occurred from the specified date of antivirus checking of the corresponding file; removing records from the database, for which said probability of probability of discharge exceeds the established threshold of records reset.

EFFECT: technical result consists in reduction of mobile device resources consumption during repeated antivirus checking of files.
