Virus.DOS.Kela

Virus.DOS.Kela  is a memory resident parasitic virus  on DOS.

There are 16 variants, the smallest infection size is 690 bytes while that of the largest is 2,530 bytes.

When the virus is loaded into memory, it hooks INT 21h and 22h, and infects any executable that is accessed.

Except Kela.690 and 823, the virus behaves stealthy and there will have no observable size change on infected files as long as the virus stays in memory. Additionally, the seconds field of the timestamp will be changed to "62" after infection. Under CHKDSK, infected files will be appeared with file allocation error due to the size change.

From June to the end of December, if an infected program is run, the virus hangs the system. Since the virus targets only COMMAND.COM, the system can be used only from January to the end of May unless the infected files are cleaned.
