There is no possible mechanism of stopping software from doing that as it is perfictally valid operations that some user may want. the reason windows propigates so many worms and virii is a) its the largest single target. b) the users. your average linux user will not randomly execute programs. if your average windows user gets something in their inbox saying hahaha.exe they will click on it. microsoft has been forced to basically remove functionality from their programs to protect the users from their own naievity I write software, I currently have to send that software out to our offices in 3 different formats due to the combinations of virus scanners and outlook restrictions they have. dont blame microsoft for the idjit users -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
