Satan-B // 66A

66A is a DOS virus that was discovered in April, 1992. It is not known where it originated from.

When an infected programme is run, the virus will search the current directory to locate uninfected .COM files. If it finds any, it will infect them.

Infected programmes will have a file length increase of 512 bytes, with the virus located at the end of the code. The programme's date and time in the DOS directory will be updated with the current date and time. 

In the infected programmes, the following text strings can be found :

"66A" 

"*.COM"

"????????COM"

Programmes infected with 66A might also fail to open, or have unusual messages appear such as "Too many files open".

To remove, just delete the infected files.
