restore my macbook pro to previous date?

I tried to download Directv's program to watch directv on my computer. My MacBook pro running Yosemite was fine until then now on all screens I'm getting a pop up for Java for Mac OSx 10.6 update14 (Deny or Accept)but it won't let me do either one. It keeps repeating the pop-up process to the extent that I can not do anything else. (They come up so fast I can't click on anything else) I can start up in safe mode and I did a disk verify permission and repair but that did not help. These pop ups even appear when off line. Help please
