I usually buy this product each year for protection when surfing and emails treatment but with this version I had blockages in my email messaging WINDOWS. The connection to the server was completely blocked by the antivirus. I had to completely reconfigure the connection parameters with the help of call center service provider. He confirmed that the error message I received was from many undesired blocking antivirus. Now the blocks are gone but I probably not repeat this again next year. Reconfigure everything is heavy and tedious.
