Every once in a while I get a little pop-up from Malwarebytes that a website, and it gives the IP address, has been blocked from access. This occurs even when the laptop is idle and I am not surfing. Does this mean someone is trying to access my laptop. The popup goes away so fast I can't copy it or write the message down. I am concerned that I have open ports that need to be closed but I don't know how to find out which ports on my laptop may be open and at risk.
