At the moment according to Virus Total.... Eset, McAfee and Ikarus detect the new slim build version installer.

 I expect it is because it is new and will turn out to be a false positive.

We had problems with false positives for the last release as well. AV companies have been pretty slack at keeping their whitelists up to date over the past few weeks.

Same here when upgrading Pro...  CCleaner.exe was removed after running the updater, then CCleaner64.exe was removed after closing CCleaner.

Update: we are in the process of notifying McAfee of the false positive so they can fix it.  Note that we have found in the past that having customers poke their respective AV vendors to update themselves can also help speed things along.

And ESET?  I mean I'll poke them, but there are other tools.

VBA32 is now also detecting all freeware builds: Standard, Slim, Portable.

McAfee has stopped detection 5.66 slim build now

I've done my best to report it to ESET as a customer.   Hope you have more luck.

It's already been reported and is a False Positive from ESET, hopefully they will update their definitions soon.

The new CCleaner version was only released a couple of hours ago and some AVs have not caught up yet.

It always happens that when a new version of software is released some AVs take a while (hours, sometimes days) to catch up with the new version, it's more noticable at the moment with the AV people working from home, etc.

Today I received a message from my virus software that it had detected & removed a THREAT in file "Ccleaner.exe". It deleted it from my system due to suspicious activity. It's detecting Ccleaner as a variant of "Generik BERVPHT" trojan. Because it deleted the file I'm unable to run Ccleaner anymore.  As a work around I visited the Piriform website and downloaded the latest version.

However, my virus software also detects the installer as a malicious file and removes it before I can even run the setup. Please FIX !!

According to VT, the Eset and McAfee false positive flagging that was there an hour ago has now gone. Hopefully this should be reflected for their users shortly

There is nothing to fix. It is a false positive

See here

ESET Update: Multiple reports from users that ESET/NOD32 has fixed their false positive flagging, although as per @Spartan to ensure you get the fix ASAP you may need to "right click on the ESET icon and choose update so it will update to the latest definitions then restart your computer. Then it won't be detected".

To be confirmed, but a similar refresh of your AV should also fix most other major AVs as well.

As a side note, we have also had a report from someone who rang ESET customer service that they were told (incorrectly) that 5.66 was blocked due to PUA.  I can only imagine that was a 1st level support engineer reading from an old script, since that would refer to the offer of the Chrome toolbar extension that was present in the installer for many years, but that we removed 11 months ago with version 5.58 (see https://www.ccleaner.com/ccleaner/version-history)

Thanks for the clarification Dave. As I always say, NEVER listen to customer service staff! They are muppets.
