Virus.DOS.Cybercide or Cybercide is a MS-DOS parasitic virus. This is a resident parasitic file-infecting virus.

Details

When activated, the virus shows a black Swastika on a red background. It hooks INT 21h and writes itself to the end of .COM-files.

Cybercide.1288, 1307, and 1321

These variants store the names of the files on DOS calls FindFirst/FindNext and OpenHandle. On call to DOS function GetDiskSpace they infect the files that are stored. They hit the files on DOS call CloseHandle also. Along with 1309, they erase the disk sectors.

Cybercide.2229 and 2256

These variants hit the files on FindFirst/FindNext DOS calls only. On opening the infected file the viruses disinfect it. They hook INT 09h, 1Ch also and call trigger routine from these handlers. On typing "anoi" on keyboard these viruses add "iS AROUND!", on pressing Alt-Del they display chars 'A', 'N', 'O' and 'I' in four corners of the screen. Depending on system timer they either displays color cross in background (looks as Swedish national flag), or play the tune (the Imperial March from The Empire Strikes Back) and display the message and then halt computer, or erase random selected disk sector by the string:

>>> A.N.O.I <<<

Cybercide.1288, 1307, 1309, 1321 erases the disk sectors.

These viruses contain the internal text strings also (some of them are written backward in "Cybercide.2229,2256"):
