Rasek.1492
Description Rasek.1492
This is a dangerous memory resident multipartite encrypted virus. While executing an infected file it writes itself to the MBR of the hard drive and hooks INT 13h, 12h. By hooking INT 13h this virus releases the stealth mechanism on reading the infected MBR. It also writes a trojan program to the floppy disk boot sectors. That program erases the hard drive FAT while loading from that floppy. Sometimes the virus also erases the FAT on loading from infected MBR.
By hooking INT 21h the virus infects COM and EXE files that are executed, it writes itself to the end of the files. The virus contains the text string "AND.COM" and does not infect the files that contains that string in their names (COMMAND.COM). The virus also contains the text strings:
"RáseK" v3.1,from La Coruña(SPAIN).Ap93
