If I accomplish nothing else today, I succeeded in removing unwanted links from my blog description. I don't know if the outside world could see the links, but I could, and I found them annoying. After an online inquiry and reading several complicated suggestions for removing the links and trying a few without success, I found the solution was right there on my blog. A big thank you to whoever provided the fix - presumably some kind person at Blogger.
UPDATE: Now I have a an unwanted panel with links that pops up on my left sidebar, and the unwanted links are back.
UPDATE 2: The unwanted links came from a program called WebCake, which I uninstalled. I have no idea how the program was installed on my computer.
