| The DCOMbobulator | 1,939,235 downloads. |
DCOMbobulator allows any Windows user to easily verify the effectiveness of Microsoft's recent critical DCOM patch. Confirmed reports have demonstrated that the patch is not always effective in eliminating DCOM's remote exploit vulnerability. But more importantly, since DCOM is a virtually unused and unneeded facility, the DCOMbobulator allows any Windows user to easily disable DCOM for significantly greater security.

| Shoot The Messenger | 2,437,508 downloads. |
Even before the latest DCOM/RPC vulnerability (see above), many Windows users were being annoyed by "pop-up spam" notices appearing on their desktops. This intrusion is also facilitated by an exploitation of port 135. Our free "Shoot The Messenger" utility furthers the security of Windows by quickly and easily shutting down the "Windows Messenger" server that should never have been running by default in the first place.

| UnPlug n' Pray | 4,456,778 downloads |
As originally urged by the FBI, and still urged by prominent security experts, our UnPnP utility easily disables the dangerous, and almost always unnecessary, Universal Plug and Play service. If you don't need it, turn it off. (For ALL versions of Windows.)

| XPdite | 1,140,816 downloads. |
A Critical Security Vulnerability Exists in Windows XP. (Surprise) Actually, as we know, there are many, but we'll handle them one at a time. This particular vulnerability allows the files contained in any specified directory on your system to be deleted if you click on a specially formed URL. This URL could appear anywhere: sent in malicious eMail, in a chat room, in a newsgroup posting, on a malicious web page, or even executed when your computer merely visits a malicious web page. It is already being exploited on the Internet.
