When you create a new tab in a web browser, you are presented with 9 or 12 images that link to pages recently visited. This seems to apply to the latest versions of all major browsers now. However, in Google Chrome, some of these links seem to be to pages that I don't remember visiting. Several weeks ago one of these links was to an old thread in the Cakewalk Coffee House forum entitled "Rethinking Prog Rock". I had not seen that thread before, as I am not a frequent visitor to this particular forum. The same link reappeared again last week and has been there every day since then, despite the fact that I did not click on it. Eventually yesterday I gave in and clicked on it and even posted a reply in the thread. Today the link has disappeared.
It's bizarre how this link kept re-appearing. I have only been using Chrome since June and I did not import any settings from other browsers when I installed it. Perhaps the software is scanning my PC for text phrases that reflect my interests and finding suitable webpages that contain the phrase. If so, I find it a little bit disturbing. I'll be watching out for similar links like this in future.
