Every day I see email for¬warded by someone trying to warn me of some new threat or with some "interesting news". Unfortunately most of these types of forwarded emails are false. In most cases it is harm¬less forwarding of emails with the only drawback being extra junk in your inbox and floating around the Internet.
In other cases, these emails themselves are a threat. Some emails will inform you of a "threat" and give you steps to take to "fix" your computer or "remove" the threat. Following the "advice" in these emails can cause problems in some cases.
Please do NOT forward these types of emails or follow the instructions in them without first doing your homework. Do a search on the "information" you received. Below are a few good links to sites with information on hoaxes, myths and real threats. There are many sites that will help you find the truth about the emails you get, I like these ones.
