I tottally agree , with you , what i do is zip any file like word doc or excel , that way when the file is being sent or on your computer ready for sending , a virus cannot add it self to the file when zipped , if you scan the doc before putting it in a zip , then you know the file will be safe , it cannot be infected while in transit as to say , to the other source , unless the other sourse as a virus on there's , if that is the case , when they unzip and open , the virus attaches itself n, and then the other person thinks you sent them a virus , this does happen alot...
