Technical Details

When executed it copies itself to 'c:\choke.exe' and creates a key in the registry under

'HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run'

with the name 'Choke' and the value 'c:\choke.exe -blahhh' to ensure that it will be started at every system startup. After this it exits with and error message saying

'This program needs Flash 6.5 to run!'

It creates a file 'c:\about.txt' with this content:
