Introducing Our Newest Security Freeware: SecurAble
saOnYellow
Quickly determine which state-of-the-art security features are being offered by your system's processor chip.

Recent AMD and Intel processors contain three features which can be extremely beneficial to the system's overall security. SecurAble probes the system's processor to determine the presence, absence and operational status of each of these three modern processor features.

The DCOMbobulator1,846,799 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 Messenger2,385,309 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' Pray3,666,040 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.)

XPdite1,129,712 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.

GRC "Perfect Passwords" Generator13,434,984 uses
Our server generates maximum entropy, ultra high quality, guaranteed unique custom password material for your use when securing and keying your WEP, WPA, VPN, or other network systems.

ID Serve944,583 downloads
Since not all Internet servers are equally secure, knowing which server software a web site is using can be important to your security. Ultimately, the security of your personal data is your responsibility. This free utility can help.

Wizmo1,169,874 downloads
Wizmo is a lightweight "Windows Gizmo" offering a wide array of handy Windows commands. With a single click it can power down monitors, trigger a screen saver, set audio volume, and much more. Wizmo also includes an intriguing highly customizable "Graviton" screen saver.

GRC.COM contains a great deal of content, to which my work continuously adds. Therefore, finding one's way around here can be a chore in itself. I maintain several comprehensive pages to help direct and acquaint visitors with this site's content, and to help them determine what's been updated or added since their last visit.

You can be notified by eMail whenever these main pages (or any others) are changed. See this link for details.


My Projects Page246 accesses per day
This page contains a chronological listing of the various projects I have completed, and those that are planned for the future. Most entries contain links to the section of this site where that work is described in detail. By browsing through what I have accomplished, both in the past and more recently, and where I am headed in the future, you can quickly develop a good feel for this entire web site.

Freeware Listing417 accesses per day
Everybody likes free software, especially when it's useful, small, and of the highest quality. Our freeware page assembles everything in one place, sorted by current popularity, historical popularity, or age since last update. Each entry contains a link to that program's section of this site, so it's a great way to view this site from the perspective of our free utilities.

If you are seeking some specific work, or if you prefer to browse a list of completed material not already mentioned above, the following section contains a short description with a link to everything else here:





  • Purchasing SpinRite – Directions for immediately purchasing and downloading our commercial software.

  • SpinRite documentation – You can learn about SpinRite by downloading its PDF documentation before, during, or after purchasing.

  • Audio/video clips of my TV appearances – If a picture is worth a thousand words, a video clip must be worth a million. Are they worth the download? You decide.

  • The worm wars of 2001 – In the late summer of 2001, the Code Red and Nimda worms were a big concern. I spent some time analyzing their behavior.

  • The Earthlink custom browser tag – Earthlink's customized IE web browser tags every web server request with some strange looking information. What is it?

  • The "Patchwork" IIS server tester – In early March 2001, the FBI and SANS Institute asked me to create a quick patch verification tester and intrusion evidence scanner for Microsoft's buggy IIS web server.

  • File downloader spying – My analysis of Real Networks, Netscape, and NetZip's file downloading utilities revealed that all downloads were being tracked and reported.

  • OptOut: The original spyware remover – Big business may be using your Internet connection and computer to spy on you. I created the OptOut utility and web pages after discovering how prevalent this secret spying had become.

  • FIX-CIH – Every April, the nasty "Chernobyl" virus wakes up to destroy many systems. The first time this happened I wrote a free & complete recovery utility.

  • Sub-pixel font rendering with Free&Clear – Microsoft says they invented their "ClearType" technology, but I quickly and independently "invented" the same thing  . . . as had others who came years before. It is very cool, but rather obvious.

  • ZIP and JAZ drive click of death – Iomega's drives sometimes fall victim to a malady known as the Click of Death. Sounds bad, is bad. Learn what you can do about it, and get my free "Trouble In Paradise" (TIP) early warning utility.
