access to websites

One of my websites do not come up on pc since installing comodo on my pc. Can someone advise me on how to allow access to this website?
Please guide me…completely new to comodo.

Hey. Welcome to the forum.

Did you enable the option to use Comodo DNS servers during installation? Check in Network Connections > Right-click your connection > Properties > Click on TCP/IP (or IPv4) > Properties > Change it to Obtain DNS servers address automatically > Click OK twice. That will reset your DNS to your ISP’s.
