Our verdict: Spybot – Search & Destroy Free is a long-running on-demand scanner for spyware, adware and tracking software, with useful extras such as immunization and startup tools. The free edition has no antivirus engine, no live protection and no automatic updates, so treat it as a second-opinion tool.
About Spybot – Search & Destroy
Spybot – Search & Destroy is developed by Safer-Networking Ltd., based in Ireland, and has been around for more than two decades. Version 2.9 Free Edition uses Spybot's own anti-spyware engine to find adware, tracking software, keyloggers and other unwanted programs.
The free edition includes Immunization, which blocks known malicious sites, tracking cookies and harmful browser plugins in supported browsers, plus Startup Tools and a Rootkit Scan. The antivirus engine, Live Protection, automatic signature updates, scheduled tasks and the protected repair environment are only in the paid Home and Professional editions, which are yearly subscriptions.
