Okay, this is a first for me.
I've been using Bitdefender for years and have had zero issues downloading and installing CCleaner updates up to and including CC528... until this one, CC529.
BitDefender is blocking the ccsetup529.exe download due to malware?

I'm attempting to download it directly from the Piriform website's download page...as I ALWAYS do and as I stated earlier, this is a first.
I have no clue as to what help you can provide me other than suggesting I disable my antimalware. I've never had to whitelist CCleaner before in order to download it.
