Trouble logging into iCloud. Need help!

Administrators: I hope I put this post in the proper location but feel free to relocate if needed.

I have an iCloud email account but can't login to it on my PC. I never get to the password screen as it only gets to that blue screen with the endless spinning wheel. Odd, but I don't have this issue with my iPad as I can get in without any issues.

I thought my PC might need a apple software update & indeed there was one available. The problem is I get an "Invalid Signature" error & can't install it. I also got a notification from Malwarebytes Pro that there was an Apple Support outbound connection that it blocked. Huh?

Any ideas?

If an outbound connection is blocked, it sound like a firewall rule is in place. How it was created is anyones guess.

If that is the only thing happening with Malwarebytes that is a good thing.

I would scan my firewall rules, outbound connections, and adjust the settings of that rule. There is likely lots of rules so you will have to analyze. Look for rules with "Blocked" or "Denied"

Thanks Ken!

I managed to update iCloud using Apple's updater but it still rejected installing iTunes. No big deal as I don't use iTunes anymore. I was able to login using the iCloud software but, however, the update didn't fix the issue of logging in either with Firefox or Edge.

I did check one other thing. Apparently my Privacy Badger software may have been the problem. I switched to "allow" & got the login screen. Funny thing is iCloud insisted I login with an @iCloud instead of @me which I normally used. It's working & that's all that matters.
