The past few times I have been on QB. the pictures in the posts show up black. For a few minutes they are fine and the suddenly some are black. If I stay on I get black squares following my cursor and then whole pieces of the screen go black, even in other programs. I noticed people have been getting malware notices. Is there a problem?

I am not having any picture issues from my iPad.

we are virus free.
the problem is with your device or with your virus/malware prevention software.
