Vulnerability refers to several kind of security risks which include viruses, trojans, worms etc. It basically means that your compter may be prone to the attacks by viruses more easily. This can lead to destruction of data and stealing private data.

Computers are vulnerable in several ways. You can ruin them with physical violence. You can ruin them by pouring liquids into them. They can be stolen. Computers can be hacked via network connections. I'm sure the list can be lengthened by more creative people.

A true virus can only spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.
