Virus.DOS.Radio.2076 is a memory resident parasitic polymorphic virus on DOS.

BehaviorEdit

When the virus is in memory, it hooks INT 8, 9, 1Ch and 21h to infect any executable file that is run or opened by writing itself to the end of the file.

The virus does not infect programs having their filenames begin with the following strings or overlay programs:

W AI

It also does not infect COM files that are smaller than or equal to 1,024 bytes.

Memory usageEdit

The exact memory usage is 6,400 bytes.

PayloadEdit

After 330 seconds of installation of the virus, it displays a colorful message in Russian at the top of the screen. If the language of the system is not Russian, it displays garbage characters instead.
