Resolved Question: Persistent Spam Email?

Okay, so I’ve been receiving a lot (and I mean a lot) of spam email lately. Usually it’s just a handful of them, but lately it’s been getting really out of hand. I haven’t put my email address on forms recently so I don’t know what’s causing it to flood in the way it is now.
For example, when I turned my PC off at 11:30 PM last night I had an empty inbox, I switched it back on about 12 noon today, and waiting for me was 68 emails sent over a period of 12 hours, 67 of which were spam. Since sending them to the junk folder I’ve had a further 7 or 8 emails. Anyone know how to stop them coming in without having to change my email address?
I use Hotmail by the way. Forgot to put that in.
