Wanted to use a made in the USA product and get away from Kaspersky, but after downloading PC Matic, I can't even get it to open. I used Firefox and after it didn't work, I found where there is a conflict. So I uninstalled it and went into the security section and unchecked the Block Dangerous and Deceptive Content box. Downloaded 3 more times and ther is no difference. Everything looks good until I open the icon on the desktop. All I get is a gray box with 4 shields in it. From that point , nothing. The only thing I can do is right click the icon in the taskbar and hit close window. Anyone have any hints? If not I'll be looking for a refund.
