Abraxas, also known as Abraxas5, discovered in April of 1993, is an encrypted, overwriting, file infecting computer virus which infects .COM and .EXE files, although it does not infect command.com. It does not become memory resident. Each time an infected file is executed, Abraxas infects the copy of dosshell.com located in the C:\DOS directory (creating the file if it doesn't exist), as well as one EXE file in the current directory.
