Short Version: I have this like fake/real its I think called "Fake Adobe Flash Player Virus" virus and need help but I kinda fixed it in a way to be less annoying but... read Long Version if you have same problem and now you can kinda fix it!

Long Version: (Read if you have same problem)

I have this "Virus" and what I mean by virus is when I am using my browser (ALL browsers Safari, Chrome I even tried Microsoft Edge) I will randomly just be doing my own thing and all of a sudden some random tab opens up... Sometimes it just some random weird thing like maybe it open up amazon.com and then sometimes it'll open up this page saying Adobe Flash Player needs update (Virus)! So I did some research its not a big deal just close the tab. And then later on I did more researching and found that is you click Safari, Preferences..., Extensions and Delete any shady extensions that you didn't have before it should be fine and it was for about 2-3 weeks then it came back BUT it happened less often so after awhile of trial and error I found that now it just shows up lest and every 2-3 weeks so I just have to delete any shady extensions about every 2-3 weeks and sometimes rarely I'll get it between those 2-3 weeks and maybe like 5,6,7 maybe 8 times before I know I have to check extensions. Anyways if you have the same problem that's a way of kinda fixing it sorry had to make it so long...
