What to do after I was named as co-author on a paper, without my consent?
Given that the publisher shut the journal down five years ago, there's not much more you can do at this point to have it removed or retracted at the source.

Instead, I would disown/disavow the paper by not including it in your CV and by making sure it is de-listed from your Google Scholar, Web of Sciences, SCOPUS, and other author citation index listing services. 

This is easy in Google Scholar by deleting the article from your page in your author-view. For SCOPUS you have to send a correction request:


http://help.scopus.com/Content/h_authorfeedback.htm


The same for Web of Science

For both Scopus and WoS, I would list the correction that you are not the same person as the author listed as the author of the paper. It would help communications with both services if you know your author identifier (Scopus Author Identifier, etc.). Something like the following should work:


  Dear SCOPUS -
  
  My author identifier is _________. One of the articles listed in my
  author record (____________ in the journal ________; DOI _________) 
  was not written by me. Please delist it from my author record.
  
  John Doe (Author identifier ________).


p.s. This is actually not an uncommon problem. Adding Famous Authors® to subpar articles is a form of authorial pagerank-jacking.
