Today, over 90% of the email sent is considered spam.  An average user cannot open their unprotected email without seeing countless spam messages, and loses countless hours manually deleting the intrusive messages from their inbox. Shockingly, the content of spam email can range from the incomprehensible to the downright obscene. Spam is dangerous to both the computer and its users. Junk mail can contain viruses, keyloggers, phishing attacks and more. These types of malware can compromise a user's sensitive private data by capturing bank account information, usernames and passwords. Spam filter software can help mitigate this overwhelming chore and protect a computer from harmful viruses and malware.
