Total Defense

Total Defense, Inc.

Vendor

Total Defense sells consumer antivirus in the United States and descends from a corporate line most buyers will not recognise under this name: its engine and business come from the antivirus products of CA Technologies, the former Computer Associates, which were spun out and continued under the Total Defense brand. Its range is small and plainly named: Total Defense Essential Anti-Virus, Total Defense Premium Internet Security and Total Defense Ultimate Internet Security, with Total Defense Essential Anti-Virus for Mac, Total Defense Mobile Security and Total Defense PC Tune-Up beside them. The tiers differ by the identity, backup and tuning extras bundled rather than by the scanner. It is a smaller company than most in this index and sells directly to households rather than through partners. It enters the public test cycles infrequently, so a reader comparing it with the major suites will find fewer independent results to weigh.
