Malware authors enjoy harvesting email addresses to use for sending spam from the compromised computers of unsuspecting victims. Spammers work like advertisers because they conduct time-based campaigns. They will send fraudulent diplomas during February and March, pharmacy emails in June to August, and malware emails during Christmas and New Year. The rest of the year is anything they want people to receive, such as non-pharmacy product ads, 419 scams, phishing, dating/sexually explicit material, gambling and more. In short, spammers work full time and never take a vacation.
Every computer user with an email account will eventually receive spam. Some may not notice it if their email client is filtering unwanted emails of if their Internet Service Provider (ISP) filters it for them. Some free web-based email providers, such as Hotmail, Yahoo!, or Gmail, automatically remove the junk emails from your inbox and put them in a separate folder.
With or without spam filtering, spam continues to arrive in thousands, or maybe even millions of email addresses. Businesses are affected because they have to spend time and money to ensure spam messages will not reach their staff or customer’s machines. In this spam reduction guide, we hope you will find the anti-spam solution for your organization or family's computers.
