Method of speeding up a full antivirus scan of files on a mobile device
Systems and methods for performing a repeat antivirus scan of a file are disclosed. A local database is saved on a mobile device, where each record is added to the database when the corresponding file is recognized as being non-malicious as a result of an antivirus scan. A short hash sum of the file...

| description | Systems and methods for performing a repeat antivirus scan of a file are disclosed. A local database is saved on a mobile device, where each record is added to the database when the corresponding file is recognized as being non-malicious as a result of an antivirus scan. A short hash sum of the file is computed and the long hash sum of the file and information about the antivirus scan performed and corresponding to the first hash sum of the file are found in the aforementioned database. Using the long hash sum, a verdict on the file is requested from the cloud services. An antivirus scan of the file is performed, except when the verdict obtained is unchanged (as compared to the verdict contained in the information about the antivirus scan performed of the obtained record corresponding to the file), and no updating of the antivirus databases has occurred since the date of performing the antivirus scan. |
