Hi Hazelnut,
Thanks for the reply and your information, yes I did get rid of all AnvSoft files left over but that didn't make any difference. But last night I had a good look at it and went into regedit and looked for it myself and found it. Whilst looking for it found that it was in a file called command a sub file of open, I deleted The avcfree.exe reg file and that seems to of done the trick fingers crossed.
So the dir. path was HKEY_CLASSES_ROOT\Wow6432Node\shell\open\command
I noticed that CCleaner registry path was only down to open, was this why it would appear again after rebooting?
Yes I do agree that only quailfied people should be able to help with this sort of thing. Thanks for telling me about it as I am a bit the wiser now!
Thanks again, Tony
