    How do I do a clean wipe of a PC without affecting my PC apps and factory settings? My computer was bought with a lot of apps and unique programs already installed on it and I want to make sure that they remain on it.

    I'm not sure that's possible. If on Windows, try using the scans provided (I think it's called malwarebytes, or Norton security). If on linux, there is probably something else you can use, but you need to give more information for more help (e.g. what operating system?). Also, if you recently backed stuff up, or if your stuff is saved to a cloud, you should be able to wipe everything, and use the cloud to get stuff back.
    Thanks!

    How does Google know if someone has used your password?

    Whenever someone signs into your Google account using your password, Google searches for the location the device sign-in originates from. If that is different from the current location you are using, it recognizes that person as an outsider and notifies you.
    Thanks!
