Anti-virus Essentials / date of Virus signature

I installed Anti-virus Essentials on the WD mirror.
It worked.
But the signature of the viruse files are date to 2014.
I have tried to update this serveral times with out any success.

My question is anti-virus still a valid product?
Are there any other tools?

Thank you
