Error loading C:\WINDOWS\uvefikahasafo.dll

Norton found a Trojan virus uvefikahasafo and quarantined it. Now when I start my computer I get an error  message saying error loading C:\WINDOWS\uvefikahasafo.dll  The specified module could not be found. The uvefikahaso has attached itself to my msconfig start up menu. I realize Norton has removed the threat but how How do I get rid of the error message and fix my  msconfig menu. Thanks. AllanD
