issue

I installed BleachBit , and i was doing scans, it completely froze and I killed the process. NOW: every time i double click on windows folders (many folders, not all folders) BleachBit application (process) opens up by itself and it lists the folder contents and asks: "Are you sure you want to permanently delete these files" How can I fix this! I tried renaming BleachBit folder (to stop the application from starting), and when i did and i try to open folders I get this message: "Application not found"
