Please follow the instructions for removing worms.
Windows NT/2000/XP/2003
In Windows NT/2000/XP/2003 you will also need to edit the following registry entry. The removal of this entry is optional in Windows 95/98/Me. Please read the warning about editing the registry.
At the taskbar, click Start|Run. Type 'Regedit' and press Return. The registry editor opens.
Before you edit the registry, you should make a backup. On the 'Registry' menu, click 'Export Registry File'. In the 'Export range' panel, click 'All', then save your registry as Backup.
Locate the HKEY_LOCAL_MACHINE entry:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
AOL START= C:\Program Files\AOL\aol_start.exe\ /start
and delete it if it exists.
Close the registry editor.
More Information
W32/Antinny-C is a worm that targets a Japanese peer-to-peer file sharing network called Winny.
W32/Antinny-C copies itself to several randomly selected subfolders in the Program Files folder using names of the format <subfolder>_<suffix>.exe
where <subfolder> is the name of the subfolder and <suffix> is one of:
cfg
config
start
login
setup
env
loader
autorun
In order to run automatically when Windows starts up the worm creates registry run entries pointing to these files.
An example of a possible file name and registry entry is:
C:\Program Files\AOL\aol_start.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
AOL START= C:\Program Files\AOL\aol_start.exe\ /start
The program also opens Explorer and displays a fake error message.
The worm attempts to copy itself to the Winny UP folder with filenames that are constructed from the strings contained in the code and filenames of the files in the Winny Down folder.
