To jsi tam nechal systemovy disk?

It is a dangerous memory resident parasitic virus. It hooks INT 21h and writes itself to the end of COM files that are accessed. On accessing to the files with name extension: TXT, DOC, 1ST, ME?, the virus appends to the end of file 50 data bytes.

From 3rd till 8th of January the virus calls trojan subroutine. It writes trojan code to the MBR sector of hard drive and "hang up" the computer. The trojan code in MBR sector on next reboot erases the CMOS memory, decrypts and displays the message:
I and the public know What schoolchildern learn Those to whom evil is done Do evil in return

Although the message displayed on my computer is different from the description, The date the crash took place matches exactly - January 8 or 9.

Takze otazka zni - je skutecne v CMOS? Nebo jen v MBR? Kdyz nabootujes z diskety/cd s odpojenym HDD, jde to? Jde to s uplne jinym diskem? Pkud ano, problem je na disku...
