BLK0SAVE, by Guy T. Rice
|
||
|
||
Bob Garth recently pointed out that one of the most likely places to hide
|
||
a virus, or at least to patch one in, is block 0, the bootup code, on your
|
||
ProDOS disks. I don't know if such a virus has been made yet, but this
|
||
program will protect you from one if it has been or will be developed.
|
||
|
||
Put this into your SYSTEM/SYSTEM.SETUP directory. Now, everytime you
|
||
boot up, it will check the boot code to see if it's been modified. If it has,
|
||
it will tell you so, fix block 0, and then reboot. (It lets you know, so you
|
||
might possibly be able to figure out which program did it. If you just
|
||
downloaded and tried out a new program, and then this message pops up, LET US
|
||
ALL KNOW IMMEDIATELY!!!)
|
||
|
||
It would probably be wisest to rename this program to something unique.
|
||
That way, a virus install program can't delete or modify this file. (For
|
||
example, you could rename BLK0SAVE to something like ZSDFSLKJHERSUR.)
