Severe Spam problem on Win Live Mail

I have Windows 7, my mail is Windows Live Mail, and I use MSE for protection.  ( don't have Outlook...)

I have a severe problem of spam in my mail.

Till some days ago I would get in the Inbox folder about 4 mails a day from spammers, now it became 30-50, and I'm afraid it can't be stopped.

Every time I get such a message I mark it as spam, then in the Spam Folder I check properies and send the whole address to blocked list, or the domain.

Examples of theese addresses : *** Email address is removed for privacy ***      *** Email address is removed for privacy ***    *** Email address is removed for privacy ***
Many addresses  are incredibly long.  
I keep getting from the same addresses, and others very similar appear daily.   
Some use "normal" domains, others are strange domains.

I never get anything filtered to the Dpam folder.

But the main issue is that it's like a machine "making up" new fake addresses constantly. 

Is there something to be done inside Windows Live Mail, or do I need to install some free program, which?

I'm desparate, it takes hours to go through the mail, and make the process I decribed, I can't see my true emails anymore,

and I have no time for this, besides my mail will crash...
