Special Note:
Reports of Rogue Antivirus programs have been more prevalent as of late.  These are programs that generate misleading alerts and false detections in order to convince users to purchase illegitimate security software.  Some of these programs may display product names or logos in an apparently unlawful attempt to impersonate Microsoft products. 
 
Use Microsoft Windows Defender, the Microsoft Safety Scanner (http://go.microsoft.com/fwlink/?LinkId=212742), or another up-to-date scanning and removal tool to detect and remove these threats and other unwanted software from your computer.
