Embodiment Construction

[0058] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0059] The embodiment of the present invention is aimed at the situation that the seek time of the disk and the rotation time of the disk scan take a relatively long time during the antivirus process. The disk modifies the file information to sort out, thereby solving the problem of reducing the disk seek time and disk rotation time during the scanning and antivirus process.

[0060] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0061] like figure 1 As shown, the method for saving disk modification records in the radial disk working mode of the embodiment of the present invention includes:

[0062] Step 11, according to the characteristics of the radial disk, u...

Abstract

The invention provides a method and a device for saving and scanning disk modification record, wherein the saving method comprises the following steps: detecting whether a file is modified in a first disk area; when a first file is modified, generating file modification record corresponding to the first file; and storing the modification record of the file in a corresponding buffer in a disk; reading the modification record of the file from the corresponding buffer in the disk and storing the modification record in a first record tape. The scanning method comprises the following steps: acquiring first information; sorting out the first information to obtain second information; displacing the second information to obtain third information of a second record tape; reading the third information when a recording head passes through the second record tape, and determining disk content needing scanning in at least one disk area according to the third information; and scanning the disk content needing scanning. The proposal of the invention can improve the scanning speed and reduce the scanning time of the disk.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for saving and scanning disk modification records. technical background [0002] With the development of computer software technology and network technology, various loopholes in computer systems are increasingly targeted by viruses and malicious programs. In order to protect the security of the system, users often install anti-virus programs and perform anti-virus scans regularly. However, with the increase of computer disk capacity, users can store more and more files in the computer, which makes each full-disk file scanning process of antivirus software take a long time. In fact, after each full-disk antivirus is completed, the second antivirus only needs to check the changed disk area. In most cases, it is not necessary to check all files. [0003] Therefore, the problem to be solved by the present invention is how to reduce the disk scanning speed and the disk ...
