AVG IS - Aborted Connection "content-eu-drive.amazonaws.com" because it was infected with "URL:Black

I have suddenly encountered the following problem when trying to upload photos to the Amazon Cloud. I do this regularly and this is the first time it has failed.It is the same on both my W10 Desktop and Laptops -

We have aborted a connection on "content-eu-drive.amazonaws.com" because it was infected with "URL:Blacklist". I copied the error reference and got the following - 57279089881c/220313.1746+0000.

Please can you advise.
