Hi,
Thanks for your help, I did driver updater which didnt show anything, and I also checked and my AVG was showing up to date. However, I dug into the AVG app and found the area to check for updates, both virus and software, and it showed that there was a software update available - strange as this normally updates when it does the virus update. Anyhow I did it manually, which also requested a reboot. After doing this I did the CCleaner actions as before this time no problem.
It should say that it is out of date and requires updating, not try installing something else "instead".
But it also screwed up my installation of Microsoft Outlook and I had to re-install it.
