I haven't recalled reading on those anywhere. Do you know what they were called?
I do know that spyware isn't coming alone anymore. What I've seen and read, more of is that spyware is being installed AFTER a trojan or some other program hits the system. It's that first program that is disabling antivirus, firewall, AND spyware scanners.
Once the initial defenses are disabled additional files are installed (depending on the bundle and/or installer it may actually call a secondary site for the rest of its bundle).
Its why more and more people are recommending programs like Syssafe that will monitor process startups and terminations and notify the user of any.
