-
- This version of the Icelandic virus differs from the Icelandic in
- that it bypasses INT21 and doesn't have the code to mark a cluster bad.
- It doesn't have the INT13 check that the second version does.
-
- Each time the Icelandic-II virus infects a program, it will modify
- the file's date, thus making it fairly obvious that the program has been
- changed. The virus will also remove the read-only attribute from files,
- but does not restore it after infecting the program.
-
- The Icelandic-II virus can infect programs even if the system is
- running an anti-viral TSR that monitors interrupt 21, such as FluShot+.
-
- On hard disks larger than 10 MB, there are no bad sectors marked in
- the FAT as there is with the Icelandic virus.
-
- Although this version has been called version 2, it may actually have
- been the first released draft, and the Icelandic 1 may be the second.
