CCleaner Professional

What is CCleaner Professional?  (from Piriform)

CCleaner is the number-one tool for cleaning your Windows PC. It protects your privacy online and makes your computer faster and more secure. Easy to use and a small, fast download. It also cleans traces of your online activities such as your Internet history.

Overview

CCleaner Professional is a software program developed by Piriform. During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The primary executable is named ccleaner.exe. The setup package generally installs about 9 files and is usually about 10.15 MB (10,644,825 bytes). Relative to the overall usage of users who have this installed on their PCs, most are running Windows 7 (SP1) and Windows 8. While about 24% of users of CCleaner Professional come from the United States, it is also popular in MA and Brazil.
