That will be because all of the installers listed there are very old versions. They are all from 2016.

(And they all contained the 'old style' bundler which didn't have clear 'Accept'/'Decline' buttons, so Microsoft didn't like it).

As it was Patch Tuesday yesterday you have probably just had the Windows Security Updates, including the latest version of the 'Malicious Software Removal Tool' which runs automatically.

MSRT downloads and runs the latest version each Patch Tuesday, along with the other monthly updates.

The MSRT doesn't just remove 'malicious' things though, it will also remove old versions of installers, and other old '.exe's', which are out of date and which might adversely affect the latest Windows if they were to be run now.

So it's probably (almost certainly) the MSRT that has quarantined those well out of date installers.

Have you had those old installers on your machine since 2016? or have you recently downloaded them from somewhere?

Thanks for the rudeness of your response friend. as I was only after "why?" it was doing this. I only post after this forum did not show any information to my post inquire.

to be more to the point. if the information was 1st up some time in the past 26.5 hours. why was I unable to find any information here in these forums? Using this info in the search = " PUABundler:Win32/PiriformBundler ". . .

Thank You Piriform for your product since July 15, 2015, under this 1 email address and of other older email address

FYI = this is the first time I have ever had any issue with any products from Piriform

Hi @CDeanC

Perhaps a read here might make things a bit clearer.

https://community.ccleaner.com/topic/59703-cccleaner-free-version-being-flagged-as-puawin32piriformbundler-solved/

Note that versions of CCleaner prior to 5.46 will no longer run on Windows 10 - so best to grab yourself the latest version from the ccleaner.com website.

Sorry if you though my factual reply was rude.

You asked why this had happened, I simply told you in a factual way why it had happened and what software would have done it.

CDeanC - bit of an over reaction there mate. Didn't see anything rude in the response - in fact the opposite, someone went to some effort to explain what was happening. If anyone is being rude it's you!
