Win32/FakeSecSen is a family of programs that claim to scan for malware and display fake warnings of malicious programs and viruses.

Win32/FakeSecSen appears to be based on Program:Win32/SpySheriff.

Reports of rogue Antivirus programs have been more prevalent as of late. 

These are programs that generate misleading alerts and false detections to convince users to purchase illegitimate security software.
