The Total AV software works. However, Total AV customer service appears to be automated. When enquiring about a refund, I received the same response both times (different subject matter submitted). I would not advise purchasing this software for this reason. There are other software providers that have equal protection capabilities. In my mind, what distinguishes one from the other is the quality and type of customer service. Total AV appears to have no real customer service. Also, be warned that selecting auto renewal is not a wise choice. Trying to get a refund later, even within the 30-day window, is next to impossible. This appears to be a UK company. They probably desperately need the funds to pay for the increases in future taxes.
Recommendation: Find another software company.
