Hi bob3160 and DavidR,
Encryption is fine, but when there is malicious code and it comes in in an encrypted way and you can not scan or check this in advance. What then? And what you say, bob3160, what about https sites with plain txt log-ins. I see a lot of these still. A lot of implementation of https everywhere adopted sites is also weak - not to say rather insecure- , and so here we go again. What looks right at a first glance, should not always be so in practice.
Well, do you see the problem there? Moreover these malvertising campaigns, lately through an obscure Bulgarian domain, only lasts a couple of hours, but could make an awful lot of victim. A decent adblocker is a must nowadays.
