Today's statistics from MessageLabs show spam making up over 50 percent of all incoming email, though the rate peaked over last weekend nearer to 70 percent. Even more of a concern is the increase in malicious spam, those unwanted messages that have content or attachments that contain various forms of malware, like viruses, trojan horses, or attempts to obtain personal information through phishing. The virus rate has averaged 0.7 percent for the last week, with phishing attempts running at about 0.4 percent.
