Just because a registry key exists does not mean it's doing anything. Revo isn't a malware remover, it's only going to remove registry keys left behind in the "proper" locations. Which is not where I would expect malware that is trying to persist itself to hide. 99% of the time Revo is unnecessary and just software looking for a reason to exist. If you think you have malware, then use a malware removal tool. If you just want to uninstall something, then just uninstall it. You don't need Revo.

Revo is less about the reg keys and more about the sometimes GBs of files apps leave behind.
