If you've ever opened your email application to see that you have hundreds of new messages in just a day or two, you know what it is like to be hit by email spam. Spam isn't just a big waste of space in your email account. It is annoying to wade through all those emails. Even more importantly, the sheer volume of viagra, porn, I'm the King of Siam's uncle and need you to move money for me, etc. emails makes missing an important email from an actual customer or the boss a lot more likely. If you happen to work for someone who isn't technologically savvy, you could even get in trouble for getting spam mail. Your boss may be under the impression that you had to visit 50 porn sites and sign up for their email lists to get all of this junk mail in your inbox. Stop the bombardment of spam mail before the little "you've got mail" tune going off every three seconds drives you to resort to pen and paper for your business correspondance or ruins your boss's opinion of your work ethic. Get some anti spam software.
