An Interesting find....

It is a valid and useful website! However like any website their information is not always perfect and if you don't read and interpret everything properly you could take an incorrect action. Many processes can be both good and bad. It is a matter of where they are running from. The downside of LIU is that they make no reference as to where the good files should be located. Thus there are time where you could look at their info and they tell you it is a valid Windows process and this could be wrong because it is not running from the correct location.

There are many useful sites like this but you just need to take a little care and also need some knowledge of the Windows OS's and also of the applications that exist to run in Windows.

Another useful link is: http://www.bleepingcomputer.com/filedb/

They often make better recommendations as to whether you should keep something running then LIU does. Not all processes are malware but many of them just are not needed at runtime. Bleepngcomputer is just better at recommending that you not waste resources on certain processes.

For the nvcpl.exe process you mentioned, here is how Bleepingcomputer dicusses it:

Note: MSconfig is not a backup utiltity!

 

Questions about installing SP2 belong in the Software Forum; however, you do need to be sure that you have no malware on your PC before trying to update to SP2.

You can also check out info in this link which has a fixdb.bat file:

Other than the above, if you still have problems installing SP2, you should post in the Software Forum.

 

I'm happy to hear you got it all worked out.
