During its install provide the option(just does) of disabling current other AV protection. the AV itself must be a working one, thus the option becomes present. However, other security protection like Superantispyware or Malawarebytes, the freebies may also be disabled provided the suite AV is in conflict with it. Typically, these security pgms. are allowed unless full-blown suite is installed then disabled others. the freebies are active but not proactive, you have to use them for full benefit, like a scan. Their basic protection/security is low-key and isn't a conflict in most cases unless it follows above. Google Total AV and see is expected, since that a new name to me. Though, I went to its website, it *seems* to use the same AV engine as AVG, but AVG is now part of Avast. FYI, I'm leery of it. Just my 2-cents.
