Can someone help me over this one? Since when I checked my MEW, I see a SPAM token in my wallet.
You can see it in this
link.
The 1 token ERC-20 ETH Anonymizer. What should I do with it?
Either it is a spam token or an airdrop. Etherscan will mark known spam tokens if they are widely distributed. It is probably worth nothing, but take a look in coinmarketcap just in case.
In any case, you can leave it in there, it won't harm. If you get tired of it, send it to a non existing eth address with gas=1wei
