I went to C:\Windows today and discovered hundreds of files called bvm files.They usually are followed by a number and a letter with some spaces e.g. bvm 2 t. When you place the cursor on one it displays a name of what appears to be an internet site. They seem sort of like cookies. The time period appears to be October 2004 (I've had the computer much longer than that) to the present. Anyone know what these are, why I am getting them and if I can delete them with no harm? Appreciate the advice.
