This morning we woke to multiple windows that were opened without our knowledge. When those windows were closed we began to hear music playing and a news cast even though no windows were open. After doing some basic looking around I saw that there were 3 new executable files that were downloaded at the same time last night, a.exe , b.exe & c.exe . I first attempted a NAV full system scan and it was taking hours to do anything. Once I saw this I looked in the task manager to see that my CPU usage was at 100% and 99% of it was being used by the c.exe . After letting the scan go on for about 5 hours I finally decided to End the Process of the b.exe & c.exe so that the scan could finish. After doing the scan the b.exe is back in the tack manager Processes. The scan finished within 45 minutes but only found a cookie that is unrelated. I did double check to see if LiveUpdate was current and it was.
I followed the steps listed in this post http://community.norton.com/norton/board/message?board.id=nis_feedback&message.id=61772&query.id=521979#M61772 and there wasn't anything in the Registry that had that name so I went to the next step and downloaded the HijackThis tool. I attached those results.
I also downloaded, and used, Malwarebytes'. It is scanning right now so I will update with those results.
I am not sure what else to do. Any suggestions as how to get rid of this would be greatly appreciated.
Thank you.
