Windows Defender

This is Microsoft's free antivirus program - and it's probably already on your computer. And by all accounts, it's pretty good.

I mention it, to save you the cost of all the other computer protection products out there. Shopping for these is very complicated - because all the vendors want to make you feel insecure.

Microsoft wants you to buy Windows 10, that has an improved version of this - and according to them, better everything! The best way to do this, is to buy a new laptop, with Windows 10 on it.

But if your Windows 7 or Windows 8 computer is still working - don't bother. A new one would cost you at least $350 (as Amazon recommends) - or even $1000 (as Microsoft recommends).
