CCleaner found those registry issues:
1)ActiveX/COM Issue InProcServer32\%SystemRoot%\System32\eapa3hst.dll
2)ActiveX/COM Issue InProcServer32\C:\Windows\System32\eapahost.dll
3)ActiveX/COM Issue InProcServer32\%SystemRoot%\System32\eapa3hst.dll
4)ActiveX/COM Issue InProcServer32\%SystemRoot%\System32\eapa3hst.dll
I don't feel safe to delete them since they are dll files. Any help appreciated.
