Can I get a virus even though my mail is scanned?
You certainly can. Even though we scan for virus we only stop known virus. It usually takes a few days for new virus examples to reach the antivirus labs around the world. We check every 2 hours for an update for new virus definitions.
Apart from email you can also get a virus from CD-Roms, Stiffy disks, web downloads or just from having a drive or directory shared for networking purposes. A safe rule is not to trust anything that you are not 100% sure of.
Do not open attachments in email that you are not expecting.
