issues after removing WebCall.dll

 

My Norton 360 removed a threat with Norton Sonar called "WebCall.dll", which is great.  However since its removal everytime I start up my computer or restart it an error message appears on the desktop screen stating "the file called c:users/raplh/appdata/......../WebCall.dll cannot be found".  My question is how do I locate the application that appears to be requesting this file and remove it so I stop getting this message.
