How reliable is the website www.video2mp3.net?

I have used this website before (about 3-4 months ago) and I had no problems and loved it. I tried it again and got a trojan virus. I wasn't sure whether this was from the site, from the youtube video, or a coincidence. I just tried it again because I had a few files I really wanted and on the third file I got another trojan warning. Just wondering if anyone else can recommend anything or give input if this website is reliable, etc.
