I will run the fix with OTL and keep try and catch my computer the next time it starts flashing the warning. I don’t have Firefox and while I have IE, I never use it but I will also start using it to see if the same issue arises with IE. It might take me a while to get back to you with the screenshot because as I said, it starts happening repeatedly only an hour (or maybe more… haven’t timed it) after I’ve been running Chrome.

Thanks so much for your help and I’ll try to get back to you as soon as possible.
