They have been running a book called “Life with Archie” for the last few years about grown up Archie that did just have an issue where he was killed. This is also the book that explored three different timelines of him getting married (Betty, Veronica, and Valerie from Josie and the Pussycats) and has basically explored several different timelines and such. That book is, I believe, over with Archie’s death.
However, they are still publishing both the normal Archie book (with the gang still in perpetual teenhood) as well as Archie Comics #1 selling title, Afterlife with Archie, which is, believe it or not, an ongoing Archie zombie comic book.
But, at any rate, Archie Andrews is, in their main timeline, still alive and well.
