Its more efective than its normal free product.yes its a faster way for virus detection.
-It provides extra features such as automatic malicious site protection
-priority support from Malwarebytes manutfacture..
-scanner update scheduler
-realtime protection module
However, even the free version of Malware does a magnificent job, although the process requires manual operation such as checking for updates and manual scan but i would say. it cleans out just the same as its full version..
