Can't see avast

Here’s the problem: I’m visually impaired. Due to that, in order to continue to use my computer, I must, through Windows accessibility, set my system colors to “high contrast black, large”. That makes my screen black with white text. With the usual white background, all I see is a white glare with no discernible text at all.

Unfortunately, this is the color scheme avast uses, making avast difficult to impossible (even literally painful) to use. Is there any way to change avast’s colors? I’d appreciate any help you could give.

Thanks.
