Heuristic and signatures

I have a question. When Nod32 detects malware heuristically, does ESET add it later in signatures?

Thank you in advance

 

It may not add it to the signatures but ESET should

 

In such case, we'd easily end up with 100 MB engines which would take the same amount of RAM while the effectiveness wouldn't be improved at all.

 

OMG , Marcos

... does it = does NOD32 ... add it later in signatures

It may not = NOD32 itself may not add it ... but ESET (is the one that) should (if necessary)

 

I guess if necessary means if the virus in specific needs a signature set to cleanup an infection. Heuristic > signature.
