Help with Bitdefender setup

In terms of the discussion of Anti Virus software I'm sometimes confused on when it comes to setting up my AV to what is the best option to use when or assume a virus is detected. Ok I've set up NOD32 using Blackspears tutorial (many kind thanks Blackspears ) but now I'm setting up my Bitdefender Pro 9 and also the free version of Bitdefender Ver 8 in which I use in conjunction with NOD32. The BD Pro 9 runs seperately on another PC.

Also whats the differnce between Virus Shield and Virus Scan ?

Here are my options that I have with BD Pro 9 assume a virus is detected:

1. Deny access & continue
2. Clean file
3. Delete file
