I’ve just checked the links above and all a functioning (in Firefox).
If one or more won’t connect for you then that it may be part of the same problem.
If you want to step things up a gear, and make sure that you machine is not infected then you could get one of the malware removal experts on the job for free. (The same experts work on various fora, which one you choose to use is up to you but I’ve linked the MB forum below).
If you want to do that I suggest that you start with this link and follow the instructions.
One of the trained experts will look over your logs and then help you step by step if there is work to be done.
