Keep getting message rtl120.bpl was not found in avg PC tune up

Keep getting two pop ups first saying avg click start not working all the time then when I click into PC tune up get Intergrator.exe unable to locate compound. This application has failed to start because rtl120.bpl was not found. Re installing the application may fix this problem. I have uninstalled all avg using revo uninstaller and they have gone from programs but PC tune up still showing in tray on bottom bar? Have now re installed and have still got same problem. Trying to fix this for elderly neighbours so any help would be appreciated. Thanks
