My Avast Premium Security Gives Me This Scary Message

[CarmeloLabadie]

Threat secured

We've safely aborted connection on 9.tlu.dl.delivery.mp.microsft.com because it was infected with SWF:CVE-2014-0543 [Expl]

The above message keeps popping up several times per hour since this morning. I looked up the "SWF..." thing and Google seems to suggest it is some vulnerability associated with Adobe Flash.

The problem is, I can't seem to find Adobe Flash installed on my computer. I typed "Control Panel" and clicked the uninstall tab to see a list of programs. Adobe Flash is not listed. Could it be "listed" elsewhere? If so, how can I find and uninstall it? Is it possible I don't even have Adobe Flash installed and this warning message from my Avast is referring to something else? Is seems scary, because it seems to suggest I was/am connected to some Microsoft program/URL. . .yet, my browser has no tab opened to that link/URL listed. I'm confused what the heck this all means and how scary of a situation this is for me (e.g., should I flat out use a new computer and consider mine infected/compromised right now)?

Major thanks for any help you all may provide!

Is the url correct as it doesn't appear so 9.tlu.dl.delivery.mp.microsoft.com or a typo as I modified in example.

A screenshot of the avast alert window might help, to show what is trying to connect here.

EDIT:
See this https://www.zerodayinitiative.com/blog/2021/7/13/the-july-2021-security-update-review as MS have released a number of CVE relating to Adobe.  However If I remember correctly a previous MS Updated removed Adobe Flash from systems

Perhaps you still have it in one of your browsers.
