I've had this problem for quite awhile. I've got windows XP norton antivirus and lavasoft adwatch installed. After each restart I can't click .exe-files and links and programs that autostart won't start. Just before startup a window popups which says something strange like "|||#|" or other strange symbols, this window I can't close only press ok then windows starts up with the problems.
To temporary solve the problem I now use the files xp_regfile, xp_exe_fix, linkfile_fix which I downloaded from
http://www.dougknox.com/ but when I restart the problem repeats itself.
Does anyone know what it might be or how I solve it
many thnx Karl
