Question cant find some files

I have been using pc's for about 20 years but the following has got me stumped.

As an extra layer of security somebody suggested i use the ESET online scanner every so often along side my kaspersky anti virus.
I watched ESET scan my pc and was surprised to see it scan some files of software and games that i know i dont have anymore.
They were shown in C drive ( x86 ) and localapp data but no matter how hard i try i just cant find these thing to manually delete them.

NOTE kaspersky does not find these when scanning and i also use ccleaner after uninstalling something.

FOOTNOTE ... just in case somebody wants to shout " shame on you " for using russian anti virus ... i will NOT be renewing it when it expires
