Whatever you resist, persists. So let em come, accept them, alter the thoughts themselves and the thought patterns surrounding these thoughts. Unwanted and intrusive thoughts are a trait of an obsessive and compulsive personality. Do some research on how to improve on this personality type and you should find some decent outcomes.

In the past 3-4 years I've seen plenty of pop-up videos
By that do you mean Pop up video advertisements? if so there are so many pop up blocker if you search the web you can find one according to your browser.
If you are talking about scary videos? when you watch you should know there are normal people who are working in that and also there are people who are shooting video such as camera man, light man, director, producer etc. When you will keep this in mind while watching anything you won't get scared easily because you will know that how videos are made.
