Hello,
Bitdefender does not encourage not recommend the above changes unless it's a temporary workaround for a known bug.
bdtl.dll is the component loaded in vsserv.exe and is used for far more activities. It intercepts traffic and processes the data for various modules and functionalities of the product, including Safepay and the firewall driver.
