With regards to your inquiry, you can scan your attachment without opening it by Downloading it to your pc or desktop.
You can use your Antivrus to scan it.
Right click the attachment you have downloaded and select to run or scan it with your Antivirus. Then the result will be displayed.
Hope this help. Please let me know if you may need further assistance and I will be glad to assist further.
