Paracab,
First off which Operating System are you running? Then which Email Program are you using?
Then which types of attachments are you talking about?
.exe
.jpg
.gif
.doc
.txt
.htm
.pdf
.dll
.pif
.sys
.mov
.mpg
.avi
etc.
Some can carry viruses, others cannot. It is very important to know what can and cannot carry viruses before you go opening attachments.
Take Care,
Richard
