F-Secure Virus Descriptions : Lapse





NAME:Lapse
ALIAS:Memory Lapse
ORIGIN:Canada
SIZE:366
TYPE:Non-resident EXE-files

The 366-variant of the Lapse virus was discovered on the CD-ROM disk "Night Owl 10" in the end of 1992.

Lapse.366 is a simple EXE infector, written in Canada. The virus infects only EXE files in its current directory and does not stay in memory. It increases the size of infected files by 366 bytes and contains the text "Memory_Lapse.366.a". The text is quite probably intended to be a mockery of CARO's virus naming standard.

Lapse.366 does not activate in any way.

The infected file is located inside the packet SF2_UP.ZIP, in the CD- ROM's "Games" directory. According to the description, the file contains an update to the game Street Fighter 2.
