Very good advice, that!
If it's not the drive-by type, likely it will be something that sounds a little too good to be true. Rest assured, it is! Don't EVER send money to someone you didn't initiate contact with, PERIOD. and you should never have to spend any money to "get" money...
Also, If you find that these things are somewhat frequent, or if you really don't want to spend the time and money on anti-virus and anti-malware stuff, You might want to think about getting a small partition of your hard-drive set aside for a Linux/Unix Operating System. There are some respectably user-friendly distributions out there right now, and they can be customized almost infinitely. You can try one, and tinker with it for a while. If you don't like that one, find another. If you can find one you like for on-line activity, you can forget all about that virus stuff. (Though most *nix users set up an antivirus that scans outgoing email for the benefit of Windows and Mac users.) You simply do all the online stuff in Linux, and Windows for the rest.
Once it is set up, if anything ever goes wrong with it, you re-boot and it's back to exactly what it was... (Sometimes I will try to find viruses so that I can see if I can make it open, and see if it will do anything to performance. Short of opening it in a 'Windows emulator' program, no luck, so far...



Howard, While you are correct about the e-mail precautions, this particular FBI scam has many variants and is what is known as a 'Drive by Virus' that can be placed by hackers on many sites.
I know this because I have had to deal with it for clients who got blocked by google because the their site was spreading the trojan and my father of all people has received it twice, (The only one emailing him is me and Walmart.)
There are many variants of this virus, what is most important is keeping your anti -virus and anti- malware sotware up to date, CPR does a really great job of clearing the more pesky infestations.
The FBI scam is NOT normally spread by email attachments, it comes from infected websites, sadly usually the more popular ones.
