Hi all I recently signed up for site analytics for my site after it dropped rank pretty badly and was looking at various logs. There are a lot of errors for favicon and robots.txt which I read are perfectly normal but I am also getting a lot of errors like the following. /categorias/ebooks-tutoriales/ /acire_matsumoto /categorias/musica /video/1419783/things-to-know-about-a-credit-card-application/ /download_google_chrome/download/13ee5e26b0b185b4451bd91ba04bd... /download_cdburnerxp/download/f2a81c5cfb9344f16c565cd4cc5437a3/ and a few others like the ones above. I have never put links like this in my site and checked my folder where I saved all the files for my site. I ran a virus scan and nothing shows up. It is only recently that my site has dropped ranking and these errors have been showing up around the same time. What should I do about this to clean it up. Please help. Thanks in advance.
