This huge list of free computer security products and services has been compiled over several years and is continuously updated. The purpose of the list is to provide a comprehensive documentation of the security products available rather than specific recommendations.  If you are seeking recommendations then check out our comparative reviews of security products (links to them are shown in the list with ) or view the personal suggestions of the list authors at the end of the list. We also offer free personalized security advice via our Security Wizard. The products on this list are almost exclusively free with a few exceptions. These include useful products without a free alternative that offer lifetime licenses or products of outstanding merit. If you are looking for a particular type of product use the index table below to go to the appropriate page. If you simply want to browse the list then click the link at the top of the index to view the list as a single huge page. Note that in some cases the links in the list point to executables.
