The popular cleaning utility Ccleaner (originally owned
by Piriform) was recently bought out by Avast and it appears a certain build of
the software has been compromised with some Malware. Ccleaner is normally used
to clean out temp files and the Windows registry etc. but this specific build
does way more than that.
The version in question was released between August 15th
and September 11th and the ones you have to worry about are the Windows build
that has a version number of 5.33.6162 and the Cloud build that has a version
number of 1.07.3191. Piriform says that the reason for the hack was probably to
stage a future botnet attack on an outside target which would turn your computer
into part of a group of computers making some kind of attack.
The threat has been removed from the software so you
should check your current version and if it’s one of the ones listed above
uninstall it and go out and get the latest version from the Piriform website.
