In 1988 one of the most common virus was unleashed. Activated every Friday 13th, the virus affects both .EXE and .COM files and delete any programs run on that day? What is the name of the virus?

The Jerusalem virus (also known as Friday the 13th virus) was first detected in 1987-1988 and activated every Friday the 13th. It infected both .EXE and .COM files and would delete programs executed on that day. The I Love You virus appeared much later (2000), Melissa was 1999, and Chernobyl (CIH) was 1998 but did not activate specifically on Friday 13th.
