CCleaner 5.33 infected

Hi,

I installed Ccleaner v5.33.6162

Today I read about the problem with this particular version in this italian article:

http://www.tecnoandroid.it/2017/09/27/ccleaner-computer-infettati-dallapplicazione-devono-formattati-249616

The italian article refers to this post:

and i double checked here:

https://www.piriform.com/news/blog/2017/9/18/security-notification-for-ccleaner-v5336162-and-ccleaner-cloud-v1073191-for-32-bit-windows-users

So I'm sure the problem is for real.

I remember having installed the update as soon as it became available.

And then I installed a new update today (v5.35.6210).

The italian article says that the systems that have been infected are not able to update Ccleaner.

I don't know if I should format my pc, or if I can consider my system safe (because I've been able to update).

Thank you and apologize for poor english.

EDIT:

I'm a Windows 64bit user. So I guess I should consider myself safe:

Can anyone confirm that?
