I had an ALERT this week. I wasn't aware that worms/viruses utilize as much as they do. I got an email with an attachment purportedly from my sister-in-law. The SUBJECT line had 'genealogy', one of her - and my- interests in it.But I don't open attachments that I'm not expecting, so I called her. And NO, she had not sent me anything, and I deleted the post without incident.
But I didn't realize that worms use key words from their hosts. On an unlucky day I might have opened the attachment...
