He highlights the dangers of malicious files and the importance of protecting ourselves, especially during the holiday season when cyberattacks are more prevalent. Shourya demonstrates how traditional antivirus software and endpoint security systems work in a probabilistic way, making it difficult to determine if a file is truly safe.
