Query: useless Hauri aka viRobot expert and PC Security Shield

I got pcSecurity Shield which uses hauri's viRobot expert 4.0 . Even though I had all updates regularly, viRobot service running still my laptop got infected by w97M virus. I lost atleast an hour on uninstall and reinstalling. Please stay away from Hauri and PC Security Shield(using Hauri in their software).
