NAME:Cantando

Cantando is a simple non-resident virus which infects other COM files by placing a copy of it's own code to their end.

Cantando deletes CHKLIST.MS files from directories it infects, thus by-passing checksummer of MSAV.

Cantando activates on the 24th of December, any year. At this date it displays the following message:
