I'd recommend not to use yaourt in the first place. It's proven to be unsafe, is deprecated and no longer actively maintained.
If u really must use an AUR helper, I'd suggest taking a look at the Arch Wiki page before choosing one.
Even better would probably be to simply use Arch's default tooling, i.e. makepkg, or but maybe that's more of a personal preference.

Notice:
To avoid crashes when upgrading Guest Additions from version 6.x to 7.x on Windows guests, uninstall the old Guest Additions first, then reboot, and then install the new ones. It's recommended to do all these operations in Safe Mode. See this upstream bug ticket for more details.
