As a newcomer to ADA , i fell for a scam youtube website .
Using
https://cardanoscan.io i managed to trace my ADA to an address that has 140.000.000 ADA.
So lets call this a dirty address.
Frankly, can not get what you meant by that. cardanoscan.io is the eligible ADA explorer. You traced your ADA to the single address that didn't belong to your wallet or what? Does your wallet contain those ADA right now? Their tracing history may mean your wallet has received them from those single address. Or you meant something different?
