Java Required pop up requesting computer update

I recently began to get pop up messages while using Internet Explorer.  The pop up appeared with the message “Java Required” and asked me to press a button and go to website computer-updates.net.  I already have Java installed on my computer so I immediately suspected something was up.  Another time the popup asked me to go to website freecomputerupdates.com to update my computer.  I suspect these are malware websites and I did not press the button.

 

Later in the day I received a message from NIS that file cpsjayq.dll was found and it is a new file.  When I looked at properties of this file the original file name was ATBroker.exe.  I suspect this is a malware executable file.  This file was found on folder: C:\Users\Jeff\AppData\LocalLow.  I have searched and I have not found anything about this matter.  Does this seem like a malware attack?
