There are many computers viruses which can be nightmare. You can wipe out
the information of the hard drive that ties up the traffic on the computer
network for hours, it may turn a normal and innocent machine to a zombie and
replicate them and send them to other computers. If your system has never
become a victim of a computer virus then you may wonder what all these are
about. But the concern of this is understandable- according to which the
computer viruses has helped to a huge amount of loss of consumer. The computer
viruses are just one kind of online threat of its bunch.
The existence of the computer viruses have been around many years, in fact
in 1949 John von Neumann theorized the self replication of the program which
was possible. On the other hand the computer industry is just a decade old, and
already someone has figured out how to infect the program that run on the
system, before the programmers known as hackers began to build
computer viruses.
Earlier some of the pranksters created virus-like programs for large
computer systems, it is the introduction of the personal computer which has
bought the computer viruses to the public attention. The doctoral student Fred
Cohen was first one to describe self-replicating programs that was designed for
modifying the computers as viruses.
In older days the viruses depends on the humans to do the hard work for
spreading the virus to other computers. The hackers save the viruses to the
disks and then distributes to the disk to the other people. It was until the
modems may be common that virus transmission becomes a real problem. Today when
we think of the computer virus then imaging that something’s that transmits
itself via the Internet. It might infect the computer via email messages or
corrupted Web links. But with the programs like these can spread much faster
than easier computer viruses. To prevent and remove them you can make use of the firewall for the protection and anti-virus for the prevention of virus and other kinds of threats.
