Has Any One Else Been Invaded?

UPDATE:  SOME ANIMALS WITH ODD NAMES BROKE INTO MY BACK DOOR.  I UNINSTALLED EVERYTHING THAT SLIPPED IN TODAY AND IT SEEMS TO HAVE FIXED THE PROBLEM.  THANK YOU FOR YOUR HELP AND ADVICE.

Assaulted with ads and having links added to your posts????

How do you stop it?  I have no ads yet they are appearing in my posts and inside my dashboard.

If I can't find a solution, this will be the death of my blog.

Any helpful hints???

Dumped, defragged, cleaned, anti-malwared, updated, repaired and it's still there. When I read your blogs there are words linked to advertisement.

Help!
