Exactly how a virus does this depends on its type, but can include propagation over removable media such as USB drives, networks, or network-based activities such as user downloads.A firewall is a barrier between something that is potentially dangerous and something you want to keep safe.

You would need a separate utility for each: one anti-virus program, and another anti-spyware.

A virus is a computer program written by someone, with the presumed intent of spreading and causing grief.

Like a human virus, a virus makes the infected computer “sick”: it causes poor performance, crashes, lost files and data, or more.

Its job is to block malicious or unauthorized network traffic from crossing the firewall into a protected network.

The most common examples of a firewall are most consumer and small-business routers.Recent versions of Windows include a built-in software firewall.Spyware is a class of malware that, as its name implies, is typically designed to spy on you or your computer, silently collecting information that is subsequently sent on to others for typically nefarious purposes.In reality, the lines between spyware and other forms of malware tend to blur, although typically a protection solution for each is still required.download (v.) is the act of copying data from a remote server to your computer or device.Conceptually, servers on the internet, or in “the cloud“, are viewed as being “up there” somewhere.While “up there” is so exceptionally vague as to be meaningless, it does at least imply a difference in altitude: the device in front of you sits, conceptually, lower than remote servers or services on the internet.
