My Hotmail account is being used as a zombie

Hi and welcome to TSF how do you access your hotmail account ie via outlook,on line or some other way ? have you run your anti virus and also malware scanners ie superantispyware or malwarebytes,please give as much info as you can a single line of text does not give us much to go on thank you for understanding

As Joeten has said, run your virus scanner in case you have some kind of a keylogger or trojan. Change your Hotmail password if you haven't already, and make sure it's something with numbers and uppercase letters.
