    + + + + + + + + + + + + + + + + + + + + + + + +

The virus creates the directory C:\vcache and saves the files vcrd01.vcrd, vcrd02.vcrd and vcrd03.vcrd. It goes on to search the hard drive for three .jpg files and then creates the file imgDisplay.html to display the pictures found.

All Information

Overview -

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.
