- How to handle with the SCA Virus
- --------------------------------
- Ok guys, i'm living in Switzerland, where the Virus was programmed
- by a very honourable Amiga Wizard of the Swiss Cracking Association
- (I'm not a member of it....). Don't panic the Virus is very harmless
- and don't damage your Computer. Now, i will try to explain how
- it works.
- First, when the Bootblock is loaded into Ram the Virus is copied
- to $7ec00 (end of Chip Memory). Once there it changes the
- WarmCapture Pointer in the ExecBase so it will be called by
- hitting CTRL-AMIGA-AMIGA. Ok now the Virus resides in ur Amiga
- and waits for someone to reset.
- RESET: The Virus changes the Pointer of SendIO and returns to
- the originial Bootroutine. This Routine loads block 0 and 1
- in memory using SendIO. Now the Virus writes himself to
- the Bootblock, destroying the old one (That's the only damage
- that it will do). After this the Virus increments a counter
- inside himself and after 15 infections it will come up with
- a nice message of the form: "Something wonderfull happened..
- your Amiga is alive !!!.. and even better... some of your Disk
- are infected by a Virus... another masterpiece of the Megamighty
- SCA !!!". After this nice Text appearing sourrounded by a red border
- in the black screen the bootblock (the old one) will be executed
- (for his last time, if the this wasn't write protected.). That's all
- the Virus can do. The Virus is only dangerous in case of disks
- which needs the bootblock to load a programm without using Dos.
-
- Ok, i hope u don't be afraid of it any longer. But how to
- throw it out of our machine while running. This is very simple.
- Just hold the left mousebutton down while resetting. If then
- the screen became green for a half second the Virus was in
- your computer and even better; is now desactivated. (by him-
- self of course..). The programmer of the Virus don't like
- to have it on every Disk .... ok that's all...
-
- I hope that nobody will use this idea to create a bad virus.
