In the early days of the Internet, spam was little more than an irritating nuisance. However, like every other aspect of the Internet, spam has evolved to become something far more nefarious in nature.
To understand just how big a problem spam has become, it will help to realize the sheer volume of unsolicited junk mail is sent out every day. More than 50% of all the trillions of email that is mailed out is spam. This spam clogs up and wastes bandwidth, especially with the recent advent of image-based spam. It places a huge strain on servers and wastes a huge amount of time and money to deliver millions upon millions of unsolicited emails to the inboxes of recipients.
Mass Mailing Viruses
Aside from constantly inundating your inbox with unwanted email, spammers now also pose grave threats to the health of your computer
One of these new dangerous aspects of spam are that illicit senders can now manipulate your email addresses, and make it seem to the rest of the world that the spam that is sent is coming from your personal computer or domain. This may result in your service provider blocking your Internet connection, or terminating your account. And all of it can be done without any knowledge on your part. It can easily be made to seem that you are an actor in a malicious mail campaign when in fact you are an unwitting actor at best.
