So, you’ve just bought a new PC or installed a fresh version of Windows. The simple fact is it's not as secure as it could be.

It doesn’t take much to tighten up your PC’s defenses - even if your computer has been up and running for a while, it’s not too late to carry out a security audit on your machine.

You probably wouldn’t leave your house without checking the windows are closed and the doors are locked. Why would you do that? Well, to stop someone breaking in and stealing your stuff or to prevent people just walking in and spray painting the walls.
