Avast Spamming Threat Detected: C:\Windows\System32\svchost.exe HELP PLEASE

This is driving me insane. I have searched the internet thoroughly and used MULTIPLE programs in effort to get rid of this virus/error/whatever it is and nothing has worked. Avast is giving me a new threat literally every 5 seconds. The “object” is a URL that changes every time a new notification comes up, the “Infection” is URL:Mal and the “Process” is C:\Windows\System32\svchost.exe. Could somebody please offer some insight on this error or any wisdom on fixing it? Thank you so much! IN ADDITION: My Windows is not allowing me to update any security updates. All windows updates that are not being allowed to update are affiliated with the error code: Code 80070216. Is this related? I’m lost with all of this. It’s frustrating me thoroughly.

Can anybody help?

I also have this problem, I haven’t a clue if this is anything serious, but I hope it isn’t.

I also have the same problem. This is really annoying
