One other, very important advise. Most people get a computer and use the existing user to work with. The problem with that is that user has administrator privileges, which means any malware has essentially free run of the system. The proper thing to do is use that account to create user accounts, and use those for daily use. As a user, malware is greatly limited in what it can do and installing software requires the admin password, so it's harder for malware to be installed. If you haven't set up a separate user account, it's not too late. Create a separate admin account and then change the existing account to user. As always, Windows requires virus scans because it's security is nowhere near what Linux and Mac have.
