Computer Hacking Since 2 a.m.

I've had computer hacking and disruption to my ability to post comments and access pages since 2 a.m. 

At the same time, an icon for another computer user, with the username  "Ricky" came up.  Ever since 2 a.m., I have had multiple disconnections, redirections, skipping around pages I didn't choose to go to,opening emails I didn't choose to open, and a bunch of other things.
