Just to add my penny worth. I have just removed ‘Avast free’ for the nth time and I had updated CCCleaner the day before. I have never before noticed any warning that Avast was bundled with the program. I will continue to use CCleaner but not update to the new versions. I have a notion that programs that need updating every few weeks are just seeking another opportunity to download yet another unwanted bundled program and collect the fee. I find it hard to believe that a simple cleaning program needs such frequent updating. I have a simple CD burning program that offers an update every few weeks - you would think it must be the most intensively developed software for this application in the history of the universe. Or perhaps it’s an opportunity to download another PUP.

I agree with an early comment that this is irresponsible because it compromises computer security - many AV programs interfere with each other. Both CCCleaner and Avast are to blame and should suffer the damage to their reputation they richly deserve.
