Thanks. The HJT link worked this time. Don't think it's needed at the moment though. I went through the cleaning process one more time and the buttons and everything dissappeared. Let's see if I can remember what I did.....
I unchecked psgaurd.exe, intell32.exe, apigx.exe, winwb.exe and iedz.exe in task manager, rebooted to safe mode, did a search for each of the files on my computer and removed them. Then I rebooted and ran the latest version of Avast. This gave me back my desktop and browser and got rid of the "spyware removal" program but I had the two quicklaunch buttons for it. After a couple of restarts I found intell32.exe and psguard.exe back in the task manager but psguard seemed to be a ghost, no running program. I checked for suspicious run entries in the registry (yeah I know, not supposed to play with the registry) and ran the older version of hijackthis. I don't remember exactly what I found. Iwas very tired at that point. Sorry.
I tried it again; unchecked intell32.exe and PSguard.exe in task manager, deleted them in safe mode and ran Avast again. This time the buttons and everything have dissappeared. After a few restarts there is no sign of this thing on my PC anymore. Hope this helps somebody.
BTW I am still running Win98se. All the info I found on removing PSGuard elsewhere required the use of ewido which doesn't work on my system. This wasn't as hairy as some of things that pop up on people's computers unwanted, but it had quite a presentation and took a while to get rid of it.
