Virus Processing Mode Selection Based on Risk and Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for processing viruses in electronic devices require manual selection of processing modes, making it difficult for users to determine the appropriate mode and location of infected files, leading to delayed virus detection and spread prevention.
Innovation Solution
A method that automatically determines whether conditions such as a time interval since the last virus scan and the presence of risk situations have passed, triggering either a comprehensive or fast virus processing mode to scan and process infected files accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual virus processing mode selection is implemented, then users can control virus scanning behavior, but users cannot determine the appropriate mode and location of infected files timely
Solution Approach 1:
The system automatically monitors file operations and risk situations, and self-determines the appropriate virus processing mode without requiring user intervention. The electronic apparatus itself services the virus detection need by autonomously selecting between first and second processing modes based on detected conditions.
Solution Approach 2:
The system continuously monitors file operations and risk situations, using this feedback to dynamically adjust the virus processing mode. When risk situations are detected or time intervals exceed thresholds, the system feedback-drivenly switches to comprehensive scanning mode; otherwise, it operates in fast scanning mode.
2Reliability
If comprehensive virus scanning is performed frequently, then virus detection accuracy is improved, but system resources are consumed excessively
Solution Approach 1:
The virus processing mode is made dynamic rather than static. The system adjusts between comprehensive scanning (first mode) and fast scanning (second mode) based on real-time conditions such as detected risk situations and time intervals since last scanning, optimizing resource usage while maintaining detection reliability.
Solution Approach 2:
The system changes the scanning parameter (comprehensive vs. fast mode) based on detected conditions. When risk situations are detected or time intervals exceed preset thresholds, the scanning parameter switches to comprehensive mode for higher reliability; otherwise, it uses fast mode to conserve resources.
3Loss of time
If automatic virus processing mode selection is implemented, then timely virus prevention is achieved, but processing complexity increases
Solution Approach 1:
The automatic mode selection is segmented into distinct, manageable conditions: monitoring file operations, detecting risk situations, measuring time intervals, and selecting appropriate modes. This segmentation simplifies the overall complexity by breaking down the decision-making process into discrete, evaluable components.

AI summary
The present disclosure relates to a method, a device and a storage medium for processing virus which can automatically distinguish which of processing mode is best for the current status of the electronic apparatus. The method includes: detecting a virus scan operation; in response to the virus scan operation, determining whether conditions (i) and (ii) are true, wherein the condition (i) is true when a time interval between a last time of processing virus using a first virus processing mode and the current time is larger than a preset interval, the condition (ii) is true when at least one of risk situations exist during a time period between the last time of processing virus using the first virus processing mode and the current time; if one of conditions (i) and (ii) being true, calling the first virus processing mode to scan files in the electronic apparatus.
