Someone notified me that she had received an email from a business contact a couple of days ago informing her that he had shared a document using Dropbox. But when she later contacted his company, she was informed that someone else was sending out email using his email address. She forwarded the message to me, which is shown below with the actual sender's address changed, though:
Subject: Blaine Watkins has shared a file with you using Dropbox

Hi, I just uploaded a Document for you to see using Dropbox.

She was concerned that her system might have been infected by malware when she viewed the message. I scanned her system with SUPERAntiSpyware Free Edition, but SUPERAntiSpyware didn't find any malware recently placed on her system. McAfee Total Protection is the real-time antivirus software on her system, but I've found that using additional tools, such as SUPERAntiSpyware, can sometimes detect malware missed by a user's antivirus software. I performed a full scan of the system using McAfee Total Protection after running the SUPERAntiSpyware scan, but it didn't find anything, either. I also checkd the system with Malwarebytes Anti-Malware Home (Free), but it didn't find any malware, either, except for a zip file I created containing files associated with malware I found on the system quite some time ago.
