hotmail hacked?

Hi guys my hotmail account started sending this email around to everyone in my contacts list...

"hi, u...! I bought a laptop from a website: www.hkeles.com last week. I have got the product. Its quality is very good and the price is competitive. They also sell phones, TV, psp, motor and so on. By the way, they import product from Korea and sell new and original products. They have good reputation and have many good feedbacks. If you need these products, look at this website will be a clever choice. I am sure you will get many surprise and benefits. Greetings!"

i changed my password, will that be enough? has anyone else come across this same problem?

Thank you
