I had to use Trend Micro's Houescall to get rid of my infectons because neither program listed above found them. I dont remember the names of them, though.
Do the programs you listed above have a way of accessing their Log files from the menus? I don't have either of those programs installed, so maybe poke around in them and see if you can locate infection logs. You could look back in the logs to get the names. Quite often, some of the malware is awfully tricky to remove, and many of the AV/Spyware companies have created tools specific to those threats.

I've seen it quite often where you remove the spyware, and after the reboot it comes right back regardless of how often you clean it out, because its hooked your system -- so having the right name and hoping for a threat specific tool is the best bet.

You could also give the Symantec Online scanner a try (at least to see if it finds a name of something), as well as downloading and installing the Adaware (both links above) and see if it finds anything. Don't install a second AV on your system tho, they tend to conflict with each other based on the way that they want to interact with your OS.
