What Is Client.foxydeal.com?
If you get a red warning screen about client.foxydeal.com on random sites, that probably means you have adware associated with Foxydeal.com on your computer. Some adware programs generate banners on your browsers when you visit e-commerce sites, with ads (price comparisons and the like) from foxydeal.com website. My guess would be that Chrome started blocking access to foxydeal.com very recently, so now when your browser tries to load the advertisement, the warning page appears instead, taking over the whole tab. You can try using ad-blocking extensions (uBlock Origin is a good one) to stop browsers from accessing client.foxydeal.com, however that will not get you rid of the adware itself. To remove the adware in some cases it may be enough to uninstall all programs and browser add-ons associated with it, while in other cases using anti-malware programs might be required.
