The invention relates to the technical field of computer programming, in particular to a redundant file deleting method and system, electronic equipment and a storage medium. The redundant file deleting method comprises the steps of obtaining a clearing command input by a user, wherein the clearing command comprises a target root directory and a target file extension; starting from the target root directory as a path, traversing the whole item directory of the target item corresponding to the target root directory, searching for all target files of which the extension names are target file extension names, and storing absolute paths of the target files into a file array; obtaining a target file name corresponding to each absolute path in the file array; traversing file contents of all non-target extension name files of which the extension names are not target file extension names in the preset directory array, and judging whether a target file name exists in the file contents or not; if not, taking the target file name as an unreferenced file name and adding the unreferenced file name into an unreferenced array; and outputting all unreferenced file names in the unreferenced array. Redundant files can be effectively deleted, and the project size is reduced.

Ransomware detection accuracy is improved by analyzing patterns of changes in filename extension counts, relative to each other, that occur in a file system over time. The disclosed approach is malware-agnostic and does not rely on recognizing malware extensions or on real-time monitoring of the target file system. Instead, during each successive backup job of the target file system, the disclosed technology counts different types of filename extensions and compares the counts to each other and to corresponding counts taken in earlier backup jobs. Preferably, the anomaly detection analysis uses machine learning to discern a behavior pattern of the file system, which indicates how filename extensions are distributed and how much they change between backup jobs over time.

The present disclosure provides a method, an apparatus, an electronic device, a storage medium and a program product for protecting against malware encryption. The method comprises: receiving normal files and malware samples into a sandbox to obtain multiple blacklists and multiple whitelists of said malware samples; performing an operation on said blacklists and whitelists to obtain a list of unencrypted filename extensions of said malware samples; and performing a filename extension operation on said normal files in accordance with said list of unencrypted filename extensions; and receiving said normal files and said malware samples into said sandbox after the filename extension operation, and outputting said list of unencrypted filename extensions if said normal files are not encrypted by said malware samples. In this way, it is possible to obtain a list of filename extensions regarding the avoidance of malware encryption, and to avoid normal file from being encrypted by malware by adding said extensions after normal filenames, ensuring data security and information security.

Detecting targeted images, as well as variations thereof within computing networks, such as the Internet and the Metaverse. Navigation to predetermined websites and accessing the HTML code to search for image file extensions and, in some instances video file extensions within the listing of URLs. In response to finding URLs with image or video file extensions, the hyperlink is activated to navigate to the webpage containing the associated image or video and the image or video is downloaded for purposes of target image detection analysis. A virtual surveillance drone is deployed within virtual reality computing systems to navigate the entirety of the environment to search for images or, in some instances videos that may be displayed and, more specifically, images that appear to match or resemble the targeted image. The drone is capable of capturing the images and communicating the images to non-virtual computing systems for purposes of target image detection analysis.

A system with a simple, intuitive, efficient interface is described for creating multi-tagged image files and playing back the tags upon demand. The system includes a display for displaying the image, a user interface is adapted to receive user input to create a user-selectable zone around each selected location, a recording device for creating an object associated with each user-selectable zone and a packing device that merges the image, the user-selectable zones and their associated objects into a tagged image file having a unique filename extension indicating that it is a tagged image file, and saving the tagged image. On playback, the image is displayed to the user who may select a user-selectable zone. The object file associated with that zone is played back. The user may also select an option that causes the objects to autoplay in a pre-determined sequence. The user may also delete, edit, or re-record objects.
