macros in word 04

ok so the whole macros thing. i downloaded an attachment from school and the macros warning popped up and i disabled them. so now when i type something on word and email it to myself to open up on my college campus it says it cant open because the file is toxic or something weird like that i dont know the exact words. does anyone know how to fix that because i print ALL of my papers on campus but not anymore apparently because i cant open any word attachments? eeeeks. thanks.

ok thing is, i dont really understand what the actual macros are? can i copy and paste to a new document and leave them out? im sorry im usually good with this stuff but im just straight up confused.
