Have you installed something called Mac Cleanup Pro?
If so, you need to remove it immediately. That there is your issue.
Please delete these folders from your computer:
/Users/renetgoupillaud/Library/Application Support/mcpnw
/Users/renetgoupillaud/Library/Application Support/mcp
Sorry, I have family over now... Have to go make nice and get away from the office.
Just get rid of that program and all bits associated with it.
Do a search for anything called MCP or similar. Use the "System Files" option as shown (attached) by choosing "other" and adding it to your search parameters. This will allow you to search within the system for anything related to MCP. Ironic that it be called MCP (Master Control Program, from Tron movie).


Look for the date range when you got that program. You have multiple dates shown in your log file, and dig all parts of that software out of your system.
I can be more help later but have to go. I'll check back later.
Good luck.
