Several days ago I also encountered MPC Cleaner on my PC and I didn't know how it got installed. I tried to uninstall it from Control Panel but nothing happened. Then I googled the web and found a post which shows how to uninstall it did the trick:
Click on Start button in the left bottom corner of the screen and click on Settings in the menu.
Click on System in the Settings screen.
Click on Apps &Features on the left side and all the installed programs will appear on the right side.
Select MPC Cleaner and click on Uninstall button.
Click on Uninstall button in the pop-up to confirm it.
When the following pop-up shows up, select Uninstall.
Continue to choose Uninstall.
Select reasons why you want to remove and click on Uninstall.

Perhaps I chose the Quick uninstall option during the software uninstallation process and this is why the uninstall failed. Anyway, the steps above work. My browser homepage also got changed to a site related to MPC Cleaner and I reset it myself. Hope this helps.
