Anti-virus vs LUA

Aaron Margosis posted an interesting thought on Anti-Virus vs Non-Admin (LUA). Basically with what's out there and the assumptions it makes, it's currently better to just run LUA (not as an Administrator) without any anti-virus or anti-malware than to run as admin because the protection software breaks otherwise.

I didn't realize there was such broken "security" software for Windows. They didn't name names in the articles though. Does anyone know which they are so I can avoid them when others ask me?
