Reddit User Uses Local Qwen LLM to Help Remediate Malware Infection

A Reddit user shared how they used a local Qwen open-weight LLM to analyze and clean up a malware infection on their offline PC after falling victim to a Discord social engineering scam. The local AI model spent about 60 minutes deciphering the obfuscated layers of the malicious file to assist in removing the threat. This case demonstrates the practical utility of locally hosted LLMs for privacy-sensitive and offline incident response tasks when internet access must be cut. It highlights how local AI models can assist users in malware analysis when standard antivirus scanners fail to identify custom or obfuscated threats. Standard security tools like Windows Defender failed to detect the active session grabber, while AdwCleaner only removed a recurring surface component. To prevent further damage while offline, the user provided the local Qwen model access to the suspicious file directory with strict instructions not to execute the malicious binary.
