The biggest problem with security? A brain dead user who isn't paying attention to spam email attachments. Some are very clever, they make the email look exactly like it's coming from your bank with logos, disclaimers and everything else you would see. The one thing is it says something like they need you to to log in because there's been an issue with your account and to please click here. Noooo!!! The best software security ever made won't help if you click on that link. <...>
^^^ This is the most important advice, and the reason why so many systems get hacked.You don't have to be brain-dead, some of them are so slick, but you do have to be aware and on your guard. Some pretty savvy people have been fooled.
Never-ever click a link in an e-mail that comes from your bank, the IRS, PayPal, your credit card, or anything else, no matter how real it looks. Same for the phone numbers. Go the long way around and go directly to their website or call the phone number listed, the link and the phone in the e-mail could be poison.
Or that e-mail that tells you that your card has been charged some huge amount of money, and if you didn't authorize it, click here. Or the one that says you have pending e-mails that can't get to you, click here to solve the problem.
I get these letters, "I want to follow up on the conversation we had a few days ago..." Or "I'm from the Norton Music IT department, you need to change your password, click here."
Even links from your friends could be poison. If your friend got hacked, the hacker can send a message from their computer using their e-mail address that contains malware.
You have to look at everything with a critical eye.
As Jazzmzmmal Bob said, even the best software won't help if you click that link.
