There are many antivirus softwares available in the market, in which most of them use signature based detection system and some others may use Heuristic-based detection system. But the problem with signature based detection system is that the antivirus will not be able to detect the new virus without its signature, this means you have to update your antivirus on daily bases or may be until you update your antivirus the virus may have done its job. So in order to tackle this problem some antivirus use day zero protection or real time protection by using different techniques like Code Analysis, Generic Signatures and Emulation.
So you have to choose the antivirus which uses these detection techniques more efficiently and effectively, it requires bit of time and research, but there are some independent sources online which will do the job for you by conducting different tests.

- ICSA Labs.
