Bd2012 Total Security Virus Shield

My system: Win7-SP1-64bit-Acer Aspire Notebook 7741g-3637-8GB Memory.

During a check of the Windows Event Viewer an error log indicated that BD2012 suites'

AntiVirus Shield was reporting an "invalid current state 14." I've pasted the information here.

Is this an indication of a virus and/or is my computer susceptible to a virus attack under this condition?

Thank you in advance for your assistance.
