Almost daily, while in Yahoo mostly, I have been getting redirected in IE 11 with a fake Adobe Flash Player message saying "Your flash player may be out of date" with a selection box asking what do I want to do with FlashPlayer.hta - 'Open', 'Save' or 'Save As'. The file says it's 1.43kb and this time the re-direct shows a web address of peziei-max.org. I've seen different sites listed each time. I close IE using task manger and do a full scan of my Windows 10 PC but the scan comes back complete.
Any ideas what this is and how to resolve it? Is the redirect happening due to a malicious ad?
