Suddenly I get warnings that RdrCEF Helper cannot be opened because of a prolbem.
I have no idea if this an Adobe issue or a virus affecting my Mac. I have never encountered anything called RdfCEF before.
Initally the warning prevented me printing a PDF, but I have now had the wajust typing with no PDT open.
I have seen warnings that RdrCEF is linked to viruses so I am worries

Hi Rogerw,
Sorry to hear about the trouble and thanks for sharing the detailed description. Since you are using the Mac OS, then we suggest you to once close unwanted the Acrobat instances running at the background and then try to open a pdf. You can refer to the following steps.
1- Open "Activity Monitor",You can search for it in spotlight or Go>Utilities>Activity Monitor.
2- Select RdrCEF Helper from the processes and force quit.
3- Open Acrobat Reader and pdf, the files should open now.
4- If it still doesn't help, then use cleaner tool to remove the application and its old traces.
Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs
Let us know if it doesn't make any difference.
Regards,
Akanchha
