An address you see in an email message or web page may look legitimate but the link connected to that address may be entirely different. The button or words you click on are totally arbitrary and the underlying web address (the hyperlink) is what matters.There are two easy ways to discover the real address of a clickable button or text phrase. You can "hover" over the item - move your mouse pointer over it without clicking - and see the real link displayed - usually at the lower left border of the browser window. You can also right click on the text or button and choose "copy the link" or "copy the shortcut". Then past this into your browser window address bar or any other document and see the actual link displayed. Both approaches - hover and copy/paste should also work with email messages that include links.
As mentioned in the earlier post, you should look closely at the Top Level Domain Name - which includes .com, .edu, .gov and country codes such as .us, .ch, .ru, etc.
