Hi Silviu C.
Are you a communication and media man?
You know how it works, they had a message and they had to find something to depict it.
It is not always original what they do.
I know of a site that borrows general copyright free pictures and then start to add a message inside with a program like PhotoShape etc.
See example attached.
It is all part of the character of communication & media on the Interwebs - momentary, casual, and fugacious.
This is not only avast! doing.
