1 Billion Downloads

We've done it!

At the start of December, CCleaner was downloaded for the 1 billionth time! That's an amazing 1,000,000,000 installations of CCleaner. A milestone that only a few other software titles have hit. (Firefox to name one)

It's been 8 years since we released version 1.0 and with the help of our dedicated users, we've managed: constant improvements, 47 language translations and a massively expanding user base in over 200 countries with over 10 million new installations a month! We can't even calculate the amount of disk space saved.

Thanks again to all our loyal fans, and we'll be announcing some new Cloud and Mobile products in the New Year. :)
