Yes, it was. I used the Opera menu and downloaded it from the official site.

I downloaded Close & Clean from "singleclickapps" and got the trojan "Radio Canyon" as an added gift...
Please look into this. It came immediately after this very download and this was on a laptop with a completely fresh Windows 8.1 OS.

I would really like to use duckduckgo, but it is not in the list. The workaround needed for it to work is not optimal.
