I bought some blockcat from etherdelta last week and put my coins in myetherwallet . it was almost 230 dolars and when I check my mew today I saw that my CAT coins are gone. here is the transaction: https://ethplorer.io/address/0x50b91a40e826b97f900dcf1e28020712aa40f1bc I have always checked the link and my antivirus has been actvie all the time (eset nod32) exchange with 2fa would be safer at least..
so be careful and think twice when you will hold your coins in desktop wallets.
