Rogers Servicepoint Agent is known to give problems to your computer causing BSOD. If you remove it, it will cause Blue Screen to make your computer unusable. Try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
