This virus will seek out and destroy copies of the Brain virus. If it
finds a Brain-infected diskette, it will remove the infection, and replace
it with a copy of itself. This virus hides on track 40 on diskettes, but
normally 360K diskettes only have tracks numbered 0 to 39. This virus does
not infect 1.2M or 3.5" diskettes correctly, but will destroy data on them.
The volume label "(c) Brain" on an infected diskette would be changed to
"YùCù1ùEùRùP". This is because YC1ERP is the call-sign of the author,
Denny Yanuar Ramdhani.
On a computer infected with this virus, pressing Ctrl-Alt-Del will not
result in a simple reboot. Instead the text "DEN ZUK" will appear on the
screen for a fraction of a second.
Then the computer will appear to reboot, but the virus will remain in memory.
Pressing Ctrl-Alt-F5 will produce a "true" reboot.
This is an older version of the Den Zuk virus and is written by the same
author. Den Zuk will also remove the "Ohio" virus if it is found.
The Mardi Bros virus appears related as well.
