It's well known that antivirus screws up some cvs operations - that's 
why we recommend not putting it on the server.

Not all antivirus does this (AVG and Avast are fine for example) and for 
those that does it's recommended that you exclude the cvs directories 
from checking - not least because it'll murder your performance both for 
cvs and compilation.

Windows defender has no issues (being an MS product you wouldn't expect 
it to).
