As Richard says you can use OSE right here! Also you can see links in GWMT. Ahrefs and Majestic are also great resources. Tools like Link Detox or Link Risk are also available and claim to help you determine if the link is bad. Although the best resource for that is you. Because you will know if this was a "manipulated" link. These automated tools may have false positives for links that might actually be helping your site. But again, you will be the best judge of that.
You can't really delete a link but can request it be removed through the webmaster or disavow it in GWMT. I think Richard gives great advice however when he points out that if you haven't had a penalty in the past, you may be better off not worrying about using the disavow tool. If you are in the group of us who have been penalized in the past, you might consider proactive disavow with Google.
Best!
