When you use the computer to access any apps that require Internet connection, you potentially
expose the computer to malware. Different malware, such as spyware, Trojan horses, viruses,
worms, and other malicious apps, can disable the operating system, apps, utilities, or cause them
to function unexpectedly.
Antivirus software can detect most of the malware, destroy them, and often repair any damage
that they have caused. To provide maximum protection against newly discovered malware, make
sure to keep the antivirus software up-to-date.
Your computer has Windows Defender Security Center preinstalled that also features virus and
threat protection. We strongly recommend that you continue to use an antivirus program in order
to provide full protection against malware.
Firewalls help to prevent unauthorized access to the system or network resources. A rewall can
be either a program installed on your computer and/or network, or a complete security solution
made up of hardware and software.
Usually there are two main types of rewalls to choose from:
When a rewall is installed on a system, all data entering or leaving the Internet, must pass
through the rewall. The rewall examines the data and blocks everything that does not meet the
specied security criteria.
Your computer has Windows Defender Security Center preinstalled that also features rewall and
network protection.

 Host-based rewalls that protect only the computer where they are installed on.

network providing protection to all the computers connected on the network.
