Problems solved by technology

Although various protection vendors have provided relative protection software for this virus, as the virus continues to upgrade, each protection vendor cannot provide good protection against the new virus.
[0003] Moreover, the latest blackmailer virus no longer encrypts all files, but randomly selects a certain location to encrypt, so that each protection software cannot judge whether the file is encrypted by analyzing the format of the file, further increasing the Increased the difficulty of identifying ransomware behavior by protection software

Abstract

Embodiments of the invention disclose a virus protection method and device, electronic equipment and a storage medium. The modification of files by various encryption methods can be recognized in time, so that the virus protection capability is effectively improved. The method comprises the steps of, when a target file is monitored to be opened in a writable mode, backing up the target file; afterthe target file is rewritten into a corresponding rewritten file, trying to open the rewritten file; and under the condition that the rewritten file cannot be opened, determining a program which opens the target file in the writable mode as a virus program. The virus protection method and device can be applied to the information security application.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a virus protection method, device, electronic equipment and storage medium. Background technique [0002] With the outbreak of the ransomware WannaCry, people once again realized the danger of the ransomware virus. Due to the characteristics of low production cost and high return profit, the virus has become one of the most concerned viruses. Although various protection vendors have provided corresponding protection software for the virus, as the virus continues to upgrade, each protection vendor cannot provide good protection for the new virus. [0003] Moreover, the latest blackmailer virus no longer encrypts all files, but randomly selects a certain location to encrypt, so that each protection software cannot judge whether the file is encrypted by analyzing the format of the file, further increasing the This reduces the difficulty of identifying ransomware behavior by p...
