Wikileaks presented documents which listed all major antivirusbrands and that CIA have tried or tries or allready managed to by pass or compromise them to get acces to our computers. And of course that´s what spy agencies do. But another problem is that it seems that not only Wikileaks got acces to the documents including numerous of codes which maybe is a bigger threath to us ordinary users. I read a report by virus bulletin which stated that when securitysoftware get acces to when you are connected via https connections and scans the connection it will not highten the security in fact it makes it less secure. If i´m not misstaken wasn´t this something that Avast incorporated in their software a while ago ? So one thing is for sure forget about privacy anymore. Sad but true. And I think it´s going to worsen in the future when it seems that “everything” in a near future will be connected to the internet. And i´m not wearing a foilhat 
Just want to ad one thing, according to the Avast blog Avast products were the only one that didn´t compromise the security when scanning the https connection. It was rated with an A. That´s one comfort. For what it is worth.
