My home page was changed on me. I reset the home page but then noticed that I had a file called t1 in the window that opens when I click on "my computer" and then "c:". It is apparently a log file that tracks me on the internet. I erase the file but as soon as I close the window and reopen it, it is back -- it keep recreating itself. It was not there before the problem with my home page being changed. I have run the latest versions of spybot and adaware and the file is still there. Can anyone tell me what this file is and how I can get rid of it?
