Michael Buen is a Filipino programmer who was with Onel de Guzman at Amaconda and were friends. He was the suspected author of the I Love You Virus which made a history in the field of computer viruses because it swept through banks, securities firms, web hosting companies. The virus forced The Pentagon, CIA, the British Parliament, and most large corporations to completely shut down their mail systems.
Last February 2000 (Before the outbreak of the virus), a virus was sent to clients of Sophos, a security firm based in Oxfordshire, England. It came in the form of a CV in the name of Michael Buen and it came from the Philippines. The virus was designed to reproduce itself and infect Word documents. It would spread by e-mail - if someone received an infected document and opened it, their files would become infected. The CV tricked people into thinking the sender was looking for a job - but it contained a threat:
"Warning! If I don't get a stable job by the end of the month, I will release a third virus that will remove all folders in the primary hard disc," it said.
In the company of his lawyer, Michael Buen declined to give details. He denied he was capable of writing the Love Bug virus.
