Using SB 4.2. System locks up when I try to do a manual update. My def files are from March. OS is Win ME. Is there a link to the javacools site where I can directly download sb .txt files using a browser? p. s. I have IE and restricted sites disabled, as I use only Mozilla and Opera browsers. IE and related .dll files have been deleted from the system. My personal protection from Active X and IE BHOs!!!!
