It is not a dangerous memory resident polymorphic parasitic virus. It hooks INT 8, 21h and writes itself to the end of EXE files that are executed. On July, 24th it displays the message:
Happy birthday to me! :-)
Depending on its internal counter the virus writes some data to some ports (disables Gravis Ultra Sound card?). The virus also contains the internal text strings:
E-VIRUS II aka Anti-GUS.12th December 1994.KL,Malaysia.
