youtube-para-mp3.com? what is this?

My Win7 laptop has been running over a year with no problems since I upgraded from xp.
This is the first problem I've encountered, but I don't really think it's a win7 issue, but thought I'd start here. If it belongs somewhere else, feel free to move it to the appropriate location.

Never had a problem with Youtube, but tonight, everytime I click on a Youtube video, it goes to this website: youtube-para-mp3.com.

what happened or what can I do?
I tried google searching on it, but can't find anything helpful.

Disable all web browser add-ons and test.

Run Virus and Malware scans.

I ran MSE and MalWare, didn't find anything. PC is clean.

But I went to the Chrome extensions and had like 3 different MP3 downloaders! Don't remember installing ANY! I disabled all of them and it works GREAT!

Thanks!

You're welcome.

May have been installed as part of a package from another software/add-on.
