rustup: Aniviruses cause a huge slowdown for 'rust-docs' installation

On my Windows 7 computer at work, the install/update process can’t pass the docs installation phase, while it works fine on my personal Linux computer.

Windows 10, using WSL also experiencing hangs on rust-docs installation. Have not yet verified whether full install will complete.

Making the rust-docs component optional is being worked on: https://github.com/rust-lang-nursery/rustup.rs/issues/998

The workaround is either adding exclusions to your antivirus or disabling your antivirus.

Is there any workaround for this issue? Seems adding .rustup to Exclusions in the Windows Defender Security Center makes it work again, but there is surely a better way.
