Removal Instructions:
Installed Software List:
You can try to uninstall products with the names listed below; for items identified by other properties or to avoid malware getting active again on uninstallation, use Spybot-S&D or RunAlyzer to locate and get rid of these entries.
- Products that have a key or property named "IEFXZ".
Files:
Please use Windows Explorer or another file manager of your choice to locate and delete these files.
- The file at "<$PROGRAMFILES>\IEfxz\iefxz.dll".
- The file at "<$PROGRAMFILES>\IEfxz\uninst.exe".
Make sure you set your file manager to display hidden and system files. If PU.IEFXZ uses rootkit technologies, use the rootkit scanner integrated into Spybot-S&D 2.x or our Total Commander anti-rootkit plugins.
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 to remove them.
Folders:
Please use Windows Explorer or another file manager of your choice to locate and delete these folders.
