In the MsDOS days there was a nasty trick... Do you remember those text files with ANSI code sequences? You typed 'TYPE THEFILE.TXT' and using the ANSI sequences you had a colorful animated display. Some files had Santa flying other a jack in the box, etc. Well, someone malicious could insert sequences to remap your keyboard so that any key press was expanded into a command (such as DEL *.*). This was only a matter if you had ANSI.SYS loaded into your system. Thinking of it... this trick can still be used with a lot of unix terminals (thought ANSI animated sequences are something forgotten in the past). One question for anyone that uses Microsoft products. How does outlook handle mails written in html with with embedded javascript? Can it do any harm? manuel, > >Torstein >>>Sorry, some >>>>e-mail, with or without attachments can transfer >>>>a virus. >>> >>> Also impossible (unless you use MS outlook or other brain-damaged mail program >>>with macro-capabilities).
