Some of my BSC wallets containing tokens also have some unknown cryptocurrencies called Zepe, AIR and FLUX. Moreover, 700,000 and 960,000 each. I thought that those tokens, which are now sometimes issued in hundreds of billions, or even trillions, are being sent out for advertising. I looked that they are not traded and they are not on CoinMarketCap and just stopped paying attention to them. Something I did not think that they can still harm my wallet. Could it be a hidden virus or a program that can withdraw other tokens from the wallet?
