Brief Description 

    

Jeefo is a virus that infects PE files.

Once it is run, Jeefo goes memory resident, infecting files every now and again. Its infection strategy consists in adding its code to the original file, increasing its size by 36,352 bytes. In addition, Jeefo encrypts the original file.

Once an infected file is run, it is decrypted and disinfected.

Visible Symptoms 

    

Jeefo is difficult to recognize, as it does not show any messages or warnings that indicate it has reached the computer.
