Recently changed folder problem

Every day in my "recently changed" file under "DOCUMENTS"
I receive hundreds of unwanted pictures.It seems as if they are
snapshots from a tv news show.How do I stop this and what is
the source of this.

hello
have you ran any scans? try downloading and running this. press the BLUE free download button. (if you can)
If you can't you may have to DL in safe mode with networking.

good luck
