With evolution of internet, security becomes a major concern. Number of malicious programs called malware, travels through network into systems. They have many advanced properties like self-hiding, self-healing and stealth mode execution, which are hard to detect. Therefore, the major challenge for researchers today is to detect and mitigate such programs. Since there is a new virus implemented every minute no detection mechanism can be designed which gives 100% protection but by keeping the anti-virus database up to date we can escape many attacks. In this paper, an effort has been made to explain the design of a system program which can scan the vulnerable files on the system, generate logs and this can later be used to design antivirus software and stop virus execution. This program aims to scan system files and target the files which are vulnerable present on the system based on their file extensions. It generates logs after the system scan is complete which can be studied and used for anti-virus creation.
