USB-AV Antivirus

USB-AV Antivirus is a specialized Windows security utility designed to protect systems from malware threats that spread through removable storage devices. The software focuses on detecting and eliminating shortcut viruses, trojans, worms, and hidden malicious files that typically infect USB flash drives and external hard disks. Installed directly on the local machine, the program provides real-time monitoring of all connected devices, scanning their contents before the operating system can execute any potentially harmful code. Its primary function addresses the specific security gap related to autorun-based malware and file-hiding techniques commonly encountered when transferring data via USB media in shared environments.

• Real-time USB device scanning. This core feature automatically examines any flash drive, external HDD, or memory card immediately upon connection to a USB port. The instant analysis identifies suspicious files before the operating system processes them, effectively preventing the execution of malicious code and subsequent system infection. The scanning engine verifies the integrity of all elements on the removable device, including boot sectors and autorun.inf configuration files.
• Shortcut virus removal. This specific functionality detects and eliminates threats that hide the user's original files and replace them with malicious shortcuts on the USB drive. The cleaning process restores the visibility of legitimate files stored on the unit while simultaneously removing the malicious scripts and altered registry entries responsible for this behavior. Data recovery occurs without modifying the original content of documents or folders.
• Restoration of malware-hidden files. This tool locates and neutralizes threats that apply system and hidden attributes to user files to evade detection. The program reverts these attributes, making legitimate folders and documents visible again while removing any malicious copies the virus may have created on the device. The operation ensures users regain complete visual control over their stored information.
• Deep removable storage scan. The comprehensive analysis examines each sector of the USB drive for known malware signatures and anomalous behavior patterns. This scanning mode verifies compressed files, packaged scripts, and potentially dangerous executables, generating a detailed report of any threats discovered. The depth of analysis is configurable, allowing users to balance scanning speed with inspection thoroughness based on their current requirements.
• Malicious autorun.inf protection. The system monitors and blocks unauthorized creation or modification of the autorun.inf file on removable devices. This characteristic prevents malware from exploiting Windows automatic execution functionality to spread when connecting the USB drive. The program maintains constant vigilance over this critical file, neutralizing any modification attempts by malicious software.
• Threat quarantine system. Files identified as potentially dangerous are isolated in a secure directory within the system, preventing their execution or propagation. This function allows users to later review quarantined items and decide on their permanent deletion or restoration in case of false positive detections. Isolation ensures threats cannot interact with other operating system processes or access sensitive data.
• Daily virus definition updates. The malware signature database updates regularly to recognize the most recent threats circulating through USB devices. The update process downloads definitions from the developer's servers, incorporating new detection patterns without requiring application reinstallation. This regular updating maintains program effectiveness against recent variants of USB-propagated viruses.
• Scheduled drive analysis. This function enables configuration of automatic removable device scans at user-defined time intervals. Scheduling can execute daily, weekly, or at specific times, ensuring periodic reviews of frequently used USB drives. The scheduled task runs in the background, minimizing interruption to the user's workflow while maintaining security standards.
• Damaged shortcut repair. The software includes a utility to restore legitimate system shortcuts that have been altered or corrupted by malware action. This repair reestablishes functionality for program and document links without requiring affected application reinstallation. The tool identifies and corrects incorrect destination paths modified by malicious software during the infection process.
• Detailed activity logging. The application maintains a complete history of all operations performed, including detected threats, quarantined files, and analyzed devices. This log allows users to track protection activity and review past security incidents. Stored information includes specific dates, times, and file paths involved in each security event.
• System drive protection. Beyond removable devices, the program offers the capability to analyze internal computer drives for USB-related infections. This function verifies that malware has not established itself in operating system directories during the initial infection process. Main hard disk scanning complements overall equipment protection against persistent threats.
• Broad removable device compatibility. The software recognizes and works with a wide range of external storage devices, including conventional USB flash drives, portable hard disks, SD cards, and cable-connected digital cameras. This versatility ensures any storage device connecting to the USB port receives analysis under the same security standards. Device type detection is automatic and requires no additional user configuration.

USB-AV Antivirus development began in 2025 by a team of programmers focused on security solutions for environments with high file exchange through removable devices. The developers, based in Eastern Europe, conceived the program to address the growing proliferation of USB-propagated malware in educational institutions and government offices. The programming language used for the antivirus core development is C++, combined with Python scripts for the heuristic analysis engine and virus signature updates.
