A computer virus is a form of computer program that replicates itself on another computer infecting that machine. Some viruses are just inconvenient, but others can kill the computer making it inoperable. Malware and Trojans aren't Virus but can damage your data too. John von Neuman wrote about self-replicating programs as far back as 1949. A fictional reference in the early 1970's first mentioned a program called virus and by 1982 viruses were out in the wild and no longer confined to the laboratory.
To solve this very simple geekdom puzzle you need to find a two-digit viral number (ab) and then use the very simple formula to get the final coordinates.
The cache is located at N51 26.xxx , W001 15.yyy , where xxx is 28 times ab, and yyy is 3 times ab.
