You can test your anti virus program for its effectiveness using a simple notepad trick.

Open Notepad.
Copy the code give below in the notepad file:
X5O!P%@AP[4PZX54(P^)7CC)7}$EIC

AR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
Save it with an .exe extension like testvirus.exe

As soon as you save this file, your anti virus program will detect the file (virus) immediately and will attempt to delete it. If this happens then your Antivirus is working properly. If not, then its time to look for some other reliable program.
