Are security updates for Windows Defender available for Windows 7?

Hi, I have a low-end PC running Windows 7 x64, with a RAM of 2 GB. In this low specs, I think Windows Defender is the best AV that respects usage of system resources. So, I wanted to know if virus definition updates are still available for Windows Defender running on a Windows 7 machine.
Bitdefender, claiming to be really light on resources, uses a massive 1.6 GB of RAM, I can't even use Microsoft Word when the AV is running!
I was really satisfied with Kaspersky as it took 1.4 GB (not good, but better than Bitdefender), but now its trial period has ended.

    Hi @Hidetoshi Dekisugi ,

    Yes, Microsoft continually updates security intelligence in antimalware products to cover the latest threats and to constantly tweak detection logic, enhancing the ability of Microsoft Defender Antivirus, also for Windows 7.
