Oh my, I was full of Trojans and other virus. Made a complete clean and the images that I had on the right and bottom of the Firefox screen disappeared.

Most of the confusion and pollution of the screen stopped. Man I thought, it was something of BOINC or SETI USA of publicity but in fact it was everywhere.

Now, I am feeling very stupid and idiot, all those images (and text) flashing and confusing me were Trojans ...
