What Spybot – Search & Destroy is

Spybot – Search & Destroy is Windows software focused on finding and removing spyware, adware, tracking software, keyloggers, and other unwanted programs. Its Free Edition includes anti-spyware scanning and removal, a rootkit scan, System Immunization, and Startup Tools. Immunization blocks access to sites associated with malicious or unwanted software, tracking cookies, and browser plugins identified as malware; the maker lists Internet Explorer, Opera, Firefox, and Chrome for this feature. The rootkit scan checks the file system, registry, and process-related lists. The Free Edition is for private, non-commercial use, and its license does not limit the number of devices used privately. Paid editions list automatic signature downloads multiple times per day and task scheduling. Live Protection monitors newly created and running processes and blocks malicious processes before they start. Command-line tools support scans, immunization, cleaning, and updating, including use with scripts and scheduled tasks. The product page also describes FileAlyzer for file analysis and RegAlyzer for browsing and changing the registry. The maker cautions that Startup Tools can change registry and other system settings, so they should be used carefully. The maker is based in Greystones, County Wicklow, Ireland.
