The number of new malicious software, also known as malware, declined slightly in the third quarter, McAfee said. However, that's cold comfort given McAfee discovered 20 million new pieces of malware between June and the end of September. In total, McAfee has identified 172 pieces of malware, in what it calls its "zoo," a library of sorts for malware.

If you use an Android device, be on alert. McAfee said it found 700,000 new pieces of malware designed to attack Android users—up 30 percent from the prior quarter. The new malware includes banking Trojans that go after account information you may enter on your phone.
Threats against other mobile phone systems, including Apple's iOS, are insignificant, McAfee said, compared with the threats against Android.
McAfee's new threat report also warned about digital currencies, such as bitcoin, encouraging more regulation for the electronic monies.

"As these currencies become further integrated into our global financial system, their stability and safety will require both financial monetary controls and oversight, and the security measures our industry provides." Weafer said.
Virtual currency grew to a $47.5 billion market in 2012 and is expected to rise 17 percent to $55.4 billion, in 2017, according to the Yankee Group.
While digital currencies are starting to be used by legitimate companies, like some Subway franchises and Virgin Galactic, they still help facilitate cybercrime. Unlike a traditional bank, virtual currencies are unregulated and allow criminals cover their tracks.

Though there have been some notable shutdowns of digital currencies, such as the take down of Liberty Reserve in May. Yet, "Virtual currencies will not go away," the McAfee report said.
