I finished installing Windows 7 SP1 and was ready to install the updates, but was not sure as to whether I should update Windows Defender. After doing some research, Windows Defender remains an anti-spyware application from Windows Vista to 7 (but was later expanded upon as an ant-virus in 8 and 10). I plan on running both Malwarebytes and Bitdefender as my anti-malware and virus, and I wanted to know if it was worth updating/enabling Windows defender, or if I should disable it completely.
