After running across the aaaidle.dll error, an issue with a module contained in your Dynamic Link Library (DLL) registry, your first step should be isolating its location.  Finding where aaaidle.dll is running from on your computer will determine whether it is related to a virus.  While it is tempting to try to manually search for a file on your computer, the reality is that this is nearly impossible.
