I'm guessing that your pop-ups are from general surfing as you can pick up all sorts of sh1t, even from legit sites. However if you went to any adult educational sites to improve techneque then, you are ripe for pop-ups.
The best options for removing or trying to remove popups are
Malware Bytes
Ccleaner
and
Malwarebytes anti-root-kit BETA tool

Those three will clean most stuff. However some malware is so well hidden in your computer that the only way to be sure that you have disinfected your machine is to do a clean install.
Sorry.
As for playing movies with your laptop to TV, the best way is HDMI to HDMI on both devices as this will play sound as well as video.
All Window's 7 devices will play sound as well as video. Sadly not all Window's 7 devices are the same. Some devices will be as easy as plug-and-play, while others will make it nigh on impossible to do, but they will all play sound. You just have to experiment with the Volume Mixer until you find the correct settings. It may even be something as strange as not even having any name resembling speakers, but the feature will be there.
My laptop has VGA, the old style connector to older monitors. This plugs into my TV and I can watch video but with no sound. I then have to plug speakers into my laptop to get the sound. That's just the way it is. I have a Tablet with HDMI and this plugs into my TV and works out-of-the-box.
If your TH does not have HDMI, then you will have to jump through lots of hoops to get sound, if at all.
