I have tokens for one week. I will always have a lot of tabs opened in my chrome so I don't remember the susceptive activities while opening the MEW wallet. I think I installed a couple of chrome plugins recently. Do you think one of the plugin tracking MEW info? I also noticed the person transfer 0.018 ether to this address
