Abstract: A system analyzes various qualitative data to identify security threats to computing devices. Qualitative data refers to data that may describe a security threat, such as user sentiment or intent data, user online comments, discussions on Web sites, offers for sale on electronic commerce (e-commerce) Web sites, blogs, news articles, and so forth. The qualitative data is analyzed, and data that is classified by the system as indicating malware is identified and acted upon (e.g., notifications provided to the appropriate users and/or devices). The use of qualitative data allows the system to be proactive in protecting against security threats. By analyzing the qualitative data, expected or future security threats to computing devices can be identified and mitigated (possibly even prevented) before any computing devices are attacked.
