I have reset my system to an earlier restore point, run McAfee and Malwarebytes checks (nothing found) confirmed AdBlock Plus still working. I will not however open any photo pages until it has been confirmed that this issue has been resolved. There isn't an issue with this forum page if accessed directly, the issue only seems to be on any page with images (main page, photos, and your own photo pages) so I suspect somehow embedded in image viewing code?
Virus scan (McAfee and Malwarebytes) finds nothing, Chrome cleared and reset but still get this issue from home page. Malwarebytes blocks multiple outward events while processor goes full ahead. Adblock plus in use.
I have to admit I am very happy with the FZ1000 - has to be one of the best bridge cameras available. I tend to shoot in aperture priority mode - even at 100iso I still get good shutter speeds - I find digital cameras seem to be a lot more tolerant of slower shutter speeds than film cameras were.
