CCleaner is a program which helps to remove unwanted files and
temporary internet files which may cause harm to the computer and make
it slower. Certain programs store files in the computer which have to be
used for the time being but have no utility in the longer run. These
files are generated by software like Internet Explorer, Windows Media
Player, Google Chrome, VLC Media Player, Mozilla Firefox, Adobe Flash
Player and Adobe Reader. CCleaner can inspect the importance of such
files and then remove the ones which have no further use. CCleaner can
also be used for deleting unwanted software.
