I don't usually endorse products or companies, but in this case I need to mention that I have been a loyal Panda customer for more than 10 years. They continue to impress me with their products and protections and have protected my enterprise and personal computing assets successfully for a long time. But keep in mind, the following is a PR Wire release, not an independent evaluation of their products. Similarly, I am offering my opinion as well. But I am not paid or otherwise incented to do so.
