My add/remove programs stopped displaying all of my programs?

Until just recently, my add/remove programs would show all the programs I've installed: games, avg, zonealarm, ect.. but now, many of my programs no longer show up. I've scanned my computer for spyware/adware and viruses using 6 different programs (2 online - trend micro and windows onecare, as well as spybot s%26d, adaware, and AVG anti-virus) with up to date definitions and have found nothing.

What's going on and how can I make my programs appear again?

The default windows program installer/uninstaller is incomplete and unstable as you can see....so use this program which shows everything installed on the computer: CCleaner
