Don Hoover
This guy actually welcomes questions from users about how to recover their spyware-laden computers. He helps in forums, and has a guest book where you can ask further questions. It is so bad out there, that anybody can get infected, but by catering to the average user with little technical background, Don fills a huge void. Hats off to Don Hoover. He is doing the world a great service.

Trend Micro
Trend Micro has some very interesting and acclaimed virus protection products. We particularly enjoy their integration with popular email andgroupware software like Microsoft Exchange and Lotus Notes.
Symantec NAV
One thing that we really like about Symantec's virus protection software is the ease of which the virus signature files and software canbe updated. We are, as always, a little wary of automatically updatingany kind of service on the server without rigorous testing; however, the automatic updates over the Internet that NAV offers seems perfect for workstations.We have had many problems with various virus software and NT 4.0; however,the Symantec product is one we have had few problems with.
ISS Security Center
In addition to being a leader in intrusion detection systems, ISS provides a most excellent database of security exploits and vulerabilities. And even better still, they have a space in their URL! :)

DeviceLock for Windows NT/2000/XP, the floppy lock software
DeviceLock gives network administrators control over which users can access what devices (ports, floppies, Magneto-Optical disks, etc.) on a local computer. Once DeviceLock is installed, administrators can assign permissions to LPT ports, CD-ROMs, COM ports or any other device, just as they would to share-permissions on a hard disk.

Excellent document. Includes links to Parts 1 and 2.
PortsLock is a personal firewall for Windows NT/2000/XP that fully supports user-level security. Once PortsLock is installed, administrators can control which users can access what TCP/IP based protocols (HTTP, FTP, SMTP, POP3, Telnet, etc.) on a local computer, depending on the time of day and day of the week. PortsLock lets you set allowed/denied TCP/UDP ports and IP-addresses for incoming and outgoing connections.
