Voting Question: How to stop spam mail?

Here’s what happened. I have a hotmail account that I used for over 7 years and I had recieved very little to NO spam mail. Two weeks ago, one of my friend’s email got hacked and some spammer got his contact list and spammed everyone on there. Now I get over 10-28 spam mails a day and I just cannot find a way to get around this, even after setting up “standard” junk mail filter. Now, I now some of you might suggest me to make a new email but I cannot switch to another email. My hotmail email is my primary email that I’ve used for over 7 years for school, work, etc. and I receive various emails from many different clients for my work. It would be very difficult to adjust to a new email.
