Usually all the packages have an uninstall.exe in the installation directory, you can run a script that runs that program.
I have never built a specific package to remove those types of programs, but when needing to uninstall a software title I know nothing about, I run the attached script against a few different machines to find the specific uninstall GUID if it does exist in the registry under HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall. The VBScript uses WMI to search Win32_Product. Some software titles you are looking for may not show up in that location, but this will enumerate everything listed in the Uninstall node of the registry.
Another thing you can do is write a script and use a Case Statement for each title name that you would like to uninstall, but you will also need to know uninstall GUID's. I hope this helps!
(VBScript is .txt, rename to .vbs to use)
