This is noteworthy. Together with colleagues, Microsoft researchers David Heckerman and Jonathan Carlson have developed a computational biology tool using some of the algorithms from Microsoft’s anti-spam filters and high-performance computing to analyze changes in the human immune system and mutations in the HIV virus to learn more about how to effectively fight HIV.
The Spammers are ingenious. If email administrators block a few words that are common spam words, they send spam as an image instead of text. If administrators block certain domains known for spam, they spoof or hack new domains to send from. Turns out, HIV acts in a similar fashion as it tries to avoid the human immune system.
