Two strange things have happened over the last week or so :- 1) While browsing the 'Android Questions' forum I've had a number of random, unrequested downloads of a file called 'Pixel.txt'. It was not related to a specific thread and would happen when simply scrolling through the threads. It has not happened when viewing any of my other usual forums eg. Android Applications, HTC M9, Android Lounge, Forum Games and up to now has only happened when using my HTC stock browser - no occurrence when using Chrome or Dolphin. It has not happened on any other website. Over a two or three day period I would estimate it has happened about twelve times and each time I have immediately deleted the file. The last occurrence was two to three days ago. 2) Yesterday I happened to copy two of my bookmarks to the Homescreen, both had a 'Xenforo' icon instead of the usual generic icon or website specific icon as shown in the attached image. This has never happened before. A Google search for 'Pixel.txt' didn't produce anything but there are some results showing for random downloads of other .txt files. Has anyone else experienced anything similar? Can anyone shed any light on either of the two occurrences?
