Threat Details:

Description:
GT Downloader copies .dll and .exe files to the System folder.
It also downloads the malware products IESP2.SpyZM, WebResponseAttachments etc.
Removal Instructions:
Autorun:
Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd), RunAlyzer (http://www.safer-networking.org/index.php?page=runalyzer) or msconfig.exe to remove the following autorun entries.
Entries named "addnz32.exe".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
A file with an unknown location named "addda.exe".
Make sure you set your file manager to display hidden and system files. If GTDownloader uses rootkit technologies, use our RootAlyzer (http://forums.spybot.info/downloads.php?id=8) or our Total Commander anti-rootkit plugins (http://forums.spybot.info/downloads.php?id=3).
You will have to use a global search for files without a name specified. Be extra careful, because just the name might not be enough to identify files!
Important: There are more files that cannot be safely described in simple words. Please use Spybot-S&D (http://www.safer-networking.org/index.php?page=spybotsd) to remove them.
Registry:
You can use regedit.exe (included in Windows) to locate and delete these registry entries.
Delete the registry key "{461A6CD0-FEEF-4A8D-7149-146EC6B117E1}" at "HKEY_CLASSES_ROOT\CLSID\".
