Cloud-based anti-malware: The company’s centralized server cloud collects data, such as samples of malware, from its user base.

During on-demand scans on and real-time protection of the company’s users’ computers, its cloud-based anti-malware submits the digital fingerprints of files and Web pages from a user’s computer to its cloud query engines for malware detection. Any file that matches the company’s blacklist is immediately removed, quarantined or dealt with based on the user’s instructions, while a non-match to its whitelist is presumed to be suspicious and further analyzed by its other technologies.
