A rapid virus scanning and killing method comprises: querying a document database, so as to determine whether a to-be-scanned file is recorded in the document database, wherein the document database records a scanning result of a locally scanned file, and the scanning result comprises file information and a security state; if not recorded, executing a scanning and killing program on the to-be-scanned file, and inputting the scanning result into the document database, if recorded, determining whether the to-be-scanned file has a change; and after it is determined that the to-be-scanned file has the change, executing the scanning and killing program, and inputting the scanning result into the document database. Furthermore, the present invention provides a rapid virus scanning and killing apparatus. By means of the method and apparatus, only changed files are scanned when performing virus scanning, and unchanged files are filtered out, so that the scanning and killing speed is improved.
Description
technical field [0001] The invention belongs to the field of computer security protection, and in particular relates to a method and device for fast virus scanning and killing. Background technique [0002] With the development of the Internet, the prevalence cycle of computer malicious programs such as computer viruses, worms, and Trojan horse programs is getting shorter and shorter. A large number of viruses and various malicious files seriously endanger the safety of users. With the continuous update and change of viruses, not only the anti-virus client also needs to update its anti-virus engine and virus signature database in time, and after the virus database is updated, it generally needs to re-scan the files on the local disk to ensure system security; therefore Antivirus software scans disk files very frequently. In the prior art, each scan usually scans all files on the disk or a custom directory. This scanning method is very time-consuming and wastes resources. Th...
