How can I keep my MyEtherWallet Safe?

[soycams]

My account was just hacked. It took my 1939 MTC coins worth $350. 

Can I still keep this address I created or is it better to create a new one and move everything there?

Create new one. But before that, make sure you have running antivirus in your PC then save your MEW's file (it's named key store/UTC file) on safe place. Don't get phised by phising link too and keylogger.
