Probably the Best Free Security List in the World - Part I


This article contains a comprehensive list of free security-related programs or web applications for Windows XP and later Windows PC-based operating systems. The few non-free programs on this list are included because they are of high merit (in our opinion) and lack a comparable free alternative. This list also includes links to webpages that contain security-related information.

We don't give specific recommendations on this list except for the personal suggestions of the list authors. If you are seeking recommendations then check out Gizmo's Freeware The Best Free Security Software for PC. Gizmo's Freeware also offers free personalized security advice via the Security Wizard.
