Description Natalie.1192
It is not a dangerous memory resident multipartite virus. It hooks INT 1Ch, 21h and writes itself to the MBR sector of the hard drive and to the end of EXE files that are terminated. On start from an infected file the virus infects the MBR sector of the hard drive. While infecting the virus writes sectors to the hard drive using hardware ports and bypasses the BIOS anti-virus protection. On starting from the MBR sector the virus hooks INT 1Ch. The INT 1Ch handler then waits for DOS loading process and patches DOS INT 21h handler with a Jump_Virus instruction.
The virus does not manifest itself in any way. It contains the text string:
