Black background in every right click

When I right click anywhere in my screen, it will always appears as a black background and text on it won't appear until the cursor passes on it or points at it. I thought my PC is slow for opening heavy applications but I only have Google chrome running with two or three sites. So I restarted my PC and removed tweaks on it, but it's still the same.
I think this is not a slow PC issue. This happened after I went to a streaming website to watch a certain movie but I closed it after my right click became like this. Could this be a result of a virus in that website? My Avast internet security didn't warn me anything when I entered it. How can I return it back to normal
