My blog is increasingly getting hacked with hidden spam ads; I have to delete them every few days, and Google is threatening to drop my blog from their search engine. Apparently this is a common problem with WordPress. Well, today I notice that my archive.php file is now misspelled arhcive.php, and starts with “Merhabba my friend” (misspelled Turkish!), but I’m not computer-savvy enough to know what to do without making it worse. Any advice?
