Windows Certificate Browser

In past two days my version 8.0.1483 is throwing up Certificate warnings about one of my mail servers. The recommendation is to look through Windows Certificate Browser to fix the problem. What is WCB? I can’t find it in Win7x64. Should I contact that server hosting service?

does this help?

Over and above the advice given by Pondus, you should be looking at updating your avast version. The latest avast version is 8.0.1497.
