Basically NOD32 has incorrectly guessed that wblind.dll is some sort of bad file.
This is known as a false positive.
We will be contacting NOD to ask them to correct their app.
For now you should be ok to ignore this error, though you will need to restore wblind.dll and tell NOD to ignore this file.
Chances are the issue wasn't you updating, but NOD32 having some sort of file update.
