All of a sudden, we are getting 'unable to locate dll' error messages on our computer. The computer is currently running Windows 2000.

Error messages appear on start-up and reappear on screen every five seconds after start-up. (i.e., clicking OK does not fix the problem, so the error message just keeps popping up. We just move the error message off the screen to keep working on the computer for the time being).

Error messages all refer to missing dll file msvcr70.dll. Some of the error messages also refer to vptray.exe, or ccSetMgr.exe, or ccApp.exe.

The error message also lists several directories (I guess where it is expecting to find the msvcr70.dll file).

c:\program files\common files\symantec shared
c:\winnt\system32
c:\winnt\system
c:\winnt\system32\wbem
c:\program files\atitechnologies\aticontrolpanel
c:\oracle\oracle8.1
c:\program files\quicktime\QT system

Not sure if this is virus related. In any event, we have run the following spyware/malware programs as a precaution:

- Avast Antivirus
- Spybot
- Adaware
- Stinger

Certain viruses/malwares were detected and removed.

We also ran 'autoruns' and deleted a few items which we thought were unusual from the start-up process.

Internet connection still works, although the computer seems to be a bit slower now.

We also started the computer in safe mode and the above error messages did not appear.

Any thoughts on how we go about resolving this?

msvcr70.dll is a module containing standard C library functions such as printf, memcpy, and cos.
It is a part of the Microsoft C Runtime Library.

Do you have an original W2k CD? If not pay attention to the second part of the tutorial about the i386 folder:
sfc /scannow

we don't have the original installation CD for Windows Professional 2000, so we copied i386 to c:/ and modified the registry and ran sfc.exe /scannow.

we received the following error message:

Windows File Protection could not initiate a scan of protected system files.
The specific error code is 0x000006 [The RPC server is unavailable].

We have a Windows Upgrade CD to convert the operating system to Windows XP, which is supposed to be specific for our Dell desktop. Do you think upgrading to Windows XP will fix the dll problem? Is it a major endeavor to upgrade the OS? What will happen to all of our data? Will it have to be backed up before upgrading?

It's possible but it also might prompt you for the W2k disk I've never done an upgrade with the disk you have.
You said that you had some viruses. You must be absolutely clean to do a successful upgrade. It would be benificial to take the extra time to do a HJT log:

Finally, there "should be" no problems losing any data but you never know
