"Don't Use Internet Explorer"

Don't:

Open attachments you are not expecting

Click on links in emails you are not expecting

Provide your username or password or any other account information via
email

Download a file that ends in .exe

Use Internet Explorer

Ignore update notifications from your OS, browser, and third parties
like Adobe

Use old browser versions

Of course, .exe files wouldn't hurt me anyway, since I run Linux.
