You can also download a program call 'StopZilla', this one serves sort of a 'firewall' to all those nasty pop-ups by grab all of them and putting them in a folder which serves as 'trash files' and you can delete them all once your finished using your PC.
Here's how to set up Outlook to do away with your junk e-mail:
1. Go to the Tools menu, click "Message rules" and then click "Mail."
2. Click the "New" button.
3. Under "Select conditions for your rule" put a checkmark next to "Where
the subject line contains specific words."
4. Under "Select the actions for your rule" put a checkmark next to "Move
it to the specified folder" or "delete it," depending on your preference.
5. At the bottom of the window under "Rule Description," it will now say:
Apply this rule after the message arrives
Where the Subject line contains specific words
Move it to the specified folder
6. Click where it says "contains specific words", and it will give you
another window that asks you to put in a phrase. Type in "***SPAM***" (the
stars and capital letters are important here, but leave out the quotation
marks) and then click "Add," then click OK.
7. Click on the word "specified," and it will give you a list of folders
that you can use for storing your junk e-mail.
8. Create a new folder by clicking the "new folder" button, and name it
"Spam," click OK.
9. Highlight the spam folder in the folder list and click OK.
10. You should now be back in the window named "New Mail Rule." The last
step, if you choose to do it, is to name the rule whatever you like. This
is in the field at the bottom named "Name of the rule."
11. Now you're done. Click the OK button in all the windows you have open.
Check your mail to test the new rule, and check your Spam folder to see if
it collected anything.
