Chrome also reports this site as risky (note the little "i" to left of address bar). Realistically, unless everyone working for the US (sorry guys, & British) intelligence services are honest, there's no real internet security. Best to use Paypal when you purchase. Before I retired, it always bothered me how open Windows PCs were on plant intranets, you could even get into other folks' stuff by accident. Hopefully, security has improved for Windows, but don't bet on it.
Not to be paranoid, but passwords should not be stored on your PCs. I still use an offline PDA for my personal stuff. I don't get the hacker mentality or why some folks think poking around in secured networks is cool. Guess my morality is "antiquated".
