Solved!
For your information, I did not understand why it happens on mobile devices, and even now on the desktop, only on sites with advertising like adsense or other.
In other sites all ok!
I had a problem in the week with the ethernet card that no longer worked.
To resolve this issue, being a cable connection, I settled with a key usb wireless and I forgot to enter a secure password or key for network access.
For this reason I could not understand why I had all infected.
Apparently if you don't use a reliable protection, anyone can sneak into the network and send commands on the browser making believe to be infected your PC.
I worked hard to remove the problem with various software, but without results.
In desperation I decided to reset the router, et oilĂ I realized I was missing the security key.
I can write now that I have solved the problem, I had already seen this morning your messages here on this thread, but I could not even click anywhere in the site because I was redirected to other advertising sites.
The links that I saw in the bottom of the browser were very long and encoded with encrypted keys long, indecipherable.
So for information should you have the same problem, think about what I describe in this post.
Thank You!
