Popping ads and freezing links.

Force Quit Safari ( command + option + esc keys). Then, Relaunch Safari holding the shift key. Then, turn off Safari extensions (Safari menu > Preferences > Extensions)

Quit then relaunch Safari while holding down the Shift key.

If you can't quit Safari the normal way use the force quit keyboard shortcut.

Command + Option + Esc

Hi. Downloaded some video software, and now new tabs automatically open and claim to be Apple, saying I have to install something. Also: when this happens, I have to restart Safari before being able to click anymore links. Finally, there is a hug tab that appears on the right - Target ads, blocking abolity to see part of window. Tried adjusting settings and uninstalling... Is a reboot necessary?

It sounds like you have malware or adware on your hard drive. You have two options available to remove it:

• Download Malwarebytes' Anti-Malware for Mac. It was developed by a trusted and respected contributor here. It's a simple, non- intrusive program that deletes known malware/adware from your hard drive. That's all it does. It doesn't add anything and it doesn't take away anything else.
• Follow the directions in this Apple support article to remove it manually --> http://support.apple.com/en-us/HT203987

In the future, do not download anything from either a torrent or an aggregate download site (CNET, Download (dot) com, MacUpdate, Softpedia, Softonic, etc.). Only download applications/plugins/extensions/drivers from the developer's own website or the Mac App Store.
