That is a complicated program !
Give ccleaner's removal function a try.
This will find the ccleaner program for you : It will not hurt to use it to clean up the PC........do not use the registry cleaning tool
Use CCleaner to remove Temporary files, program caches, cookies, logs, etc. Use the Default settings. No need to use the
Registry Cleaning Tool...risky. Pay close attention while installing and UNcheck offers of Google Chrome and Avast.
After install, open CCleaner and run by clicking on the Run Cleaner button in the bottom right corner.
