When the malware's file is run, it first shows a fake error messagebox:
The text in the messagebox can also be:
File not found
Then the virus scans all local hard drives and copies itself with different names to different directories on it. The virus "borrows" names of files located in a folder where it copies itself to, but in order not to overwrite these files, the virus changes its file name a bit - it adds one extra character to the beginning of its file name.
For example if a virus finds a file named NDD.EXE in a folder, it will copy itself as PNDD.EXE or SNDD.EXE and so on. On the screenshot the malware's files are in red squares:
If the virus finds a JPG, AVI or MP3 file, it creates a copy of itself by "borrowing" a name of that file and adding .EXE extension. For example for CLOCK.AVI the virus will create a file named CLICK.AVI.EXE. This malware creates only one file in each folder each time it is run.
