Lately I’ve had a plethora of what I call the “Check this Out!” emails. These are all malware/viruses. NEVER click on these links even if they are from your best friend. Their computer has become infected and they are just passing it along to you and the rest of their address book.
What I like about Gmail is that they flag these emails with a red warning to remind you of the potential problem. I’ve looked at the same email in Yahoo email and they don’t have any warning. This is just another reason to start using Gmail as your email of choice.
