I deleted all my cookies, temporary files, and history and now, my videos won't load. Also, I had downloaded Avira Antivirus Pro.?

I'm not sure which is blocking me from watching any video content. I have Windows 8.1, so Adobe Flash Player is already integrated and I'm still having issues. Flash Player is enabled and Active X Filter is off. I don't know what else to try. I deleted all my cookies, temporary files, and history and now, my videos won't load in IE.. Also, I had downloaded Avira Antivirus Pro.?
