Do you recognize the program "C:\Program Files\Java\sidebar.exe" - I can't find anything about it by searching, and nothing in my event logs suggests what might have causes this file to exist. Apparently I had a restart just before the time it was created, but I didn't have any installs in the session prior to that restart.
I noticed it due to my CPU fan rising fast. Stuck around 13% CPU usage. Virus total: https://www.virustotal.com/da/file/26c7282daa667210785080f0dbe8e6f85c8a3949e433b198ee91d9ebffd1b5b5/analysis/1372769247/
Currently I handle it as a virus. (resolved, see comments below)
