I recently started using the Safari web browser on my Windows XP computer to see if I would like it because I'm planning to get a Mac Book for college in a few weeks.
I went on youtube and there was a small cube with question marks around the side where the video should have been. Then I tried watching several other youtube videos and the same cube appeared.
I also can't watch videos on Facebook or any other site that has flash videos because it says I need to download the latest version of Adobe Flash Player. When I attempt to download Flash player it says:
"Windows found that this file is potentially harmful. To help protect your computer, Windows has blocked access to this file."
