Mobile Devices - Impossible to log-in

It seems each time I click on the log-in fields to type in my login/password I get redirected to another site.

This is happening 99% of the time.

There is no visible add at the time, but it seems as though visible or not, there is something redirecting me each time I try to log-in.

I've taken the ads that I suspect were causing this off, so it should be better now.
