With Bitdefender v10 I run a full system scan, and a deep system scan. In both cases, Bitdefender will not check memory, cookies, or registry keys.
I am using engine version 7.20801.
From the following log, you can see that Bitdefender is set up to check the memory, cookies and registry, but you can also see that it is not doing so:
