When it comes to home security, individuals need to protect themselves online as well. Getting an effective anti spam tool doesn't have to be expensive. In fact, there are some great PC security tools available for free. The list of free security programs runs into the double digits, so the only hard part is determining which one best suits your needs. There are two approaches to building your security toolkit.

The all-in-one method uses a suite of programs from one company, while the 'pick-and-mix' method uses a combinations of individual programs that are each best of class in their specialty. There are pros and cons to both approaches. For instance, the all-in-one approach means fewer programs to maintain, and all components work seamlessly together. The pick-and-mix method can be more flexible, but there is a higher chance of incompatibilities. Free security suites vary a lot in terms of which security components they include, but one option that does have an anti-spam filter is Agnitum Outpost Security Suite.
