Clean Master Antivirus issue

While scanning my device, an issue was detected that requested four files - two with android icons, one with perhaps notification icon and another which I can't remember - to be uploaded to CM security cloud or something like that. I was unsure if I should allow this or decline, but then did it anyway.

Afterwards, I downloaded CM security app as the clean master app requested. But the previous action made me realize that there can be security concern. I have my fingerprint added to my phone galaxy j7 prime which runs android marshmallow.

Should I be worried? I later uninstalled both of the apps clean master and cm security.

Once I thought I should reinstall clean master and perform the same process to take a screen shot, but the full version of clean master app can no longer be found on playstore, only the lite version is found.

Any help and insight is appreciated.
