I am looking in my ESET directory in "Program Files" and notice that 1/ nod32.001 is missing (?) I don't know what these files are, anyway, or even whether they can be deleted. 2/ nod32.000 is 11 M, as opposed to the .002, .003,etc files which range from 791 bytes to 432K. So, is this huge increase in size expected ? Thanks! Judy PS -- with the last Windows update, I did have some issues with AMON not running...I'm assuming that all is okay now, but I'm not sure how to check to make sure. Double thanks!
