Protecting yourself from virus attachments
Email Tip #8: Smarter Attachments (Part 1)
Attaching a file to an email can be a wonderful method of sharing information. However, as viruses become larger threats, the following guidelines can help reduce problems:
Do not open any attachment until you are sure you know the sender.
Use caution if the attachment has an extension of .exe or .com. These files are designed to immediately perform a program or action.
Large documents can take a long time to download, especially if the recipient does not have a high speed connection. Attachments should be no larger than two megabytes.
If a document is larger than two megabytes, consider faxing as an alternative.
Summary: With attached files, use caution when opening files, and only send smaller documents when possible.
