Hello,
in CCleaner Cloud you have at the section "Software" an option to "Add Software".
Here you offer also "Adobe Reader DC".
I know that the Adobe Reader is very popular in many companies.
And it is also installed on many private computers.
If you read actual security bulletins then you can see that there are may security issues in Adobe Reader and in Adobe Flash.
Adobe releases every month security updates (also for the Adobe Reader) and more frequent security updates for urgent problems.
So why do you offer such a dangerous app?
What if a user installs the Adobe Reader and then gets infected or hacked?
Can you (Piriform) get problems here?
