About 4 or 5 weeks ago, i read a article on THN(the hacker news) that the ccleaner servers were hacked to distribute malware and as a result millions of computers were affected who had downloaded and installed ccleaner in month of August. I have also ccleaner installed on my older pc which i had downloaded before August and my pc is not infected.But I buyed a new laptop now, then it will be safe to install ccleaner now?
Is it safe to install ...
It is nearly impossible to be sure that some software is safe to install. It can always contain a back door, have bugs in it which might be exploitable from a remote system or similar.
All one can say that the specific problem with CCleaner was fixed according to Avast and that currently no other problems are publicly known with this software. If you consider this safe enough is up to you.
