- The SCA Virus was the first Amiga virus and one of the easiest to
- deal with. It is a bootblock virus meaning it can only affect a floppy
- disk, not individual files and not hard drives. However it can be
- passed from one floppy to another by booting your Amiga with a disk
- that's infected with SCA and then inserting other floppies later.
-
- The remedy is fairly simple: use the AmigaDOS "install" command
- on any suspected/infected floppies. The downside of this is if
- the floppy has some custom bootcode on it (as some commercial
- game disks do), it will be wiped out when you install the disk
- and the game may refuse to run in the future.
-
- Do you FTP a lot of files from foreign sites? It was recently
- discovered that the SCA virus is living in a .DMS file of a
- Porky Pig animation that is currently on amiga.physik.unizh.ch
- and a lot of other sites. If you downloaded and unpacked this
- file recently, then that's prolly where you got the virus.
-
- Any of the current virus checkers will detect SCA since it's
- been around so long. The only way to totally purge it from your
- system is to power of your Amiga and then power back on a few
- seconds later. That'll wipe it out of memory.
-
- Then boot your machine with a known CLEAN Workbench (if you don't
- have a hard drive), get a virus checker, run it, then insert your
- recent floppies one at a time and see if the virus is detected.
- If it is, the virus checkers will give you an option to install
- the disk and wipe the virus from it.
-
- Look around for SteveX Tibbett's VirusX program. You'l find it
- on Fish Disks and a zillion other places. It'll run fine under your
- old 1.2 (yikes!) operating system and it'll detect and remove the
- SCA virus.
