Identify and Remove Bad Backlinks

My website http://expertdaconquista.com/ is trying to rank for the keyword como conquistar uma mulher on google.com.br but so far with no results. I truly believe this is work of my backlinks spammed on unethical websites. So I expect someone to do a detailed scan and analysis on my website to see if there's any shady backlinks like:

• many backlinks across the website
• blacklisted domains
• webpages with spammy backlinks
• websites removed from google index
• not working websites
• malicious domains

I will also provide a list of previous backlinks found by myself.
