We’ll start off this post with free antivirus software and work our way to the more expensive ID protection options.
I’ve personally been using AVG for years. AVG has a completely free version, and a paid version available at $53.99. The free version comes with basic identity protection, however the paid version furthers protection from identity threats. AVG Internet Security 2013 provides alerts when an attempt to access personal data on your computer is made, and alerts you of websites which may be fraudulent or not properly encrypted.
Avast has many interesting and useful features for more advanced users such as sanbox mode, unfortunately the free version does not give you any extra protection against identity threats. The paid version is available at $59.99 for a year.
