I found a very helpful article in Bottom Lines magazine regarding e-mails and viruses.
Here’s an example of how the scam works: Bill received an e-mail from the post office, informing him that a package could not be delivered. The e-mail instructed him to click on a link to arrange delivery. But when Bill clicked on the link, his computer was infected with a malicious virus!
SELF DEFENSE: Before clicking on any e-mail link, hover your cursor over it. Then look at the status bar at the bottom of your browser window-it will show the actual web address to which the link connects. If it looks suspicious, don’t click on it!
The post office never sends out e-mails about deliveries. They only leave notices in your mailbox.
Stay well,
