XML.plainmedium.com

Could someone please from AVG tell me what to do now that this threat keeps on appearing no matter what brower I use.  I need it REMOVED from my computer.  I have done as I was previously told to do by AVG and it has not been removed.  The lastest screenshot I send is dated Decemeber 3 and I did not get a reply.
I have removed Chrome from my laptop and am now using Edge as my browser.  The threat has shown up again .  Screen shot attached.User-added image
Hello Wendy,

I understand how difficult this is for you. Please provide me the screenshot http://avgclick.me/getscreenshot of the threat message you receive, we will check your account and assist you further.
When on my laptop I keep on getting a notice that AVG has blocked XML.plainmedium.com.  I am then asked to scan my computer.  This is happening at least 10 times, if not more per day.  Is there something else I can do to rid my computer of this threat?  Scanning so many times is getting frustrating.  This has been happening for the last week.

I have removed Chrome from my laptop and am now using Edge as my browser.  The threat has shown up again .  Screen shot attached.User-added image
