It is necessary to remove from the Google index links to the pages of my site https://quartercheapersigns.ca/ that were created by a virus – about 43 800 pages in Google index. The virus and the pages it created were removed from the site. A week ago, changes were made to the sitemap for reindexing. But so far the pages have not been deleted – moreover, new “garbage” pages appear in Google Webmaster. The site has no more than 100 “real” pages in the index. Everything else is non-existent links to garbage pages.
The main question we have now is how to remove this spam information from the Google index?
