I have twice tried using this product's "tune up" processes; once to update drivers, once because "my computer was feeling under the weather." Both times it totally disabled my computer. Once I had to take it to a professional to get it working again. The second I had to uninstall Chrome and Office 360 and re-install them. Probably have others I will need to reinstall. Also destroyed Quicken and I am having to re-enter months worth of data. I have not idea how this keeps getting positive reviews from the corporate reviewers, but I will never let it near a computer again.
