Update >> changed theme, desktop icons?

Using Comodo Dragon, worked great, used default skin/theme.

Yesterday, the theme changed (on it’s own) to a black color, and the desktop icons changed to a deeper more sinister red.

I uninstalled dragon, and re-installed it, and it was fine, until I turned PC on this morning, and it had changed back to black, and the desktop icons were that sinister red again.
I have auto update turned off, and it was off.

Was there a pushed update or something?

I use malewarebytes, and emsisoft anti virus, which I run daily…

Any suggestions? Explanations? Help??
