"Computer Viruses, Worms, Data Diddlers, Killer Programs, and Other Threats to Your System" by John McAfee and Colin Haynes
A 1989 book on how to recognize, deal with, and protect yourself from viruses and other threats to your system. Written by John McAfee, the creator of the McAfee antivirus program and more recently known for being bat-crap crazy, and Colin Haynes, with a foreword written by John C. Dvorak (nephew of August Dvorak, creator of the Dvorak keyboard layout).
The book includes detailed descriptions of how different malware works and interacts with your system and it also includes code snippets from historic malware. It's a good read if you're interested in the history of malware or computers in general.
