Virus File Isolation and Targeted Scanning for UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security software inefficiently searches for and removes virus files, consuming excessive computer resources and risking re-infection of User Equipment (UE), as it often requires full scans and can interfere with user activity.
Innovation Solution
A device and method that includes a processor and memory with instructions for targeted virus file processing, utilizing virus file information to isolate and transfer cleaned files to a separate space, reducing resource consumption and preventing further infections by allowing scans only when the UE is idle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full scan is performed to detect virus files, then detection completeness is improved, but computer resource consumption increases
Solution Approach 1:
The patent segments the virus detection process into two phases: an initial full scan to build a virus file information database, and subsequent targeted scans using isolation paths to specific directories where viruses are likely to exist. This segmentation reduces resource consumption in ongoing detection while maintaining completeness through the comprehensive initial scan and continuous path updates.
Solution Approach 2:
The patent performs preliminary full scanning to establish a complete virus file information database before normal operation. This preliminary action includes recording all virus paths, types, and characteristics, which are then used to guide subsequent targeted detection operations, eliminating the need for repeated full scans.
2Object-affected harmful factors
If virus files are removed from original location, then infection risk is reduced, but re-infection possibility increases
Solution Approach 1:
The patent introduces an isolation space as an intermediary between the virus source and the clean file system. Cleaned virus files are transferred to this isolated environment where they cannot infect other files, yet remain accessible for analysis and path updates. This intermediary approach simultaneously reduces infection risk and prevents re-infection by maintaining awareness of virus characteristics.
Solution Approach 2:
The patent extracts cleaned virus files from their original locations and places them in a separate isolation space. This extraction removes the harmful elements from the file system while preserving the ability to track and analyze them, preventing both immediate infection and future re-infection through path monitoring.
3Loss of time
If virus scan is performed during user activity, then detection timeliness is improved, but user experience deteriorates
Solution Approach 1:
The patent implements dynamic detection scheduling that adapts to user activity states. The system monitors UE idle status and dynamically adjusts when to perform virus scanning operations. During active user periods, detection is minimized or postponed; during idle periods, comprehensive scanning is performed. This dynamic approach maintains detection timeliness while preserving user experience.
Solution Approach 2:
The patent employs periodic virus detection cycles that are triggered by UE idle status rather than continuous scanning. The system periodically checks for idle conditions and schedules detection operations accordingly, ensuring that scans occur during appropriate time windows when user interference is minimal, thus maintaining both timeliness and user experience.
