your hard drive is unreadable or damaged.

    These instructions worked for us to a point - there were still prompts, but I was then at least able to install extra antivirus to remove

    To me, not using the administrator account is probably the biggest change for most users. We are all used to using an administrator account on Windows, and switch to a Standard User account is a big change for most. While it may be a big change, it is an important part of security your Windows OS. Making the change can prevent alot of installations from happening behind the scenes, as well as protect changes to your system folders.
