I had the same thing happen yesterday at the UC forum. I had a fake AVG security warning that had identified trojans with a "click here' to remove. The "click here" was a link to an .exe file to download the virus to my computer! I couldn't close the link so I had to do what you did, close explorer and re-enter (after checking to see if any files were downloaded onto my computer).
I am now having a problem with backing out of threads. Going back only refreshes the page.
