Recently I had ran a virus scan on my computer with a free-ware virus program (AVG) because I was conciously aware that Norton and Symantec programs would not run on my computer due to a Trojan virus. After scanning and removing four different trojans from my system, I began receiving a warning that said I did not have the appropriate administrative rights to open any programs. After re-scanning, eight more trojans were removed, and now I receive a warning that says "Windows cannot find [Program path name and .exe] Make sure you typed the name correctly and try again." I also receive a warning that rundll.exe is missing when I try to access anything. I can't run any MMC programs (Disk cleanup, defrag, etc.) or any control panel programs. What should I do to repair this problem? (PS, My windows XP key is missing, re-installing probably isn't much of an option. If it was, how would I do it without being able to use executable programs?)

Do A repair reinstall of Windows.
You will need a key but on a repair it is near the end of the installation. By that time you should be able to run an exectuable by pressing shift+f10. It will open a command prompt. From there you can switch the drive to the floppy by simply typing a:
You will need to put the magicjellybean .exe program on a floppy and put it in the drive. If you dont have the program - you can find it here
http://www.magicaljellybean.com/keyfinder.shtml
Note the download is a zip file with the exe inside.
You can execute the program off the floppy and then copy and paste the key values for each section.
I just did this the other day with the program running off a USB Drive.

One of my main problems is I cannot get the Windows install to run at all. Any means of attempting to open the .exe promps an Administrator name and Password when I attempt sneaking around directly executing the file. Elsewise, I still receive that message about the file missing.

The magicjellybean helped with half the problem though. I was able to test it on another computer, so I know I will be able to at least fix that much of the problem on this computer. Thank you for the suggestion.

Unfortunately, I've searched three out of four sites for information on the trojans. Most of them require you to download their product in order to repair the problem, and my system won't permit me to download McAfee or Symantec. Grisoft's AVG was the program I was using at the time that all of this started, and TrendMicro I found couldn't find the majority of the trojans I had on this computer.

AVG's Detailed report lists the following Trojans:
Winshow.AC on MSXMIDI.exe
Rameh.E on ATPART~1.dll
Dropper.Small.5.BN on BLDGS.dll
BackDoor.Optix.BI on MPLDFG.exe and Winset.exe
Dyfica.2.1 on CLN4.tmp
Dyfica.2.L on INSTAL~1
And the last one was a simple dialer on a removable drive.

I appreciate the help suggested in solving this problem, though through finally getting fed up with trojan-removal searching and trying to run another system through this computer, I finally wiped the drive and re-installed Windows XP (Regretfully, mind you). Down side is, I'm missing a ton of .dll files and the activation code is incorrect, even using magicjellybean. Thank you though, for the help given.
