Everyday there is a new virus, or variant of an old virus, propigating it
self through the web, email, and P2P networks. That is why it is not only
important, but also essential to be protected. At Broken Computer, we can
outfit your PC, network, or both with the correct preventative measures,
such as Antivirus software, firewalls, and the latest operating system
patches.
Virus defined: A program that can "infect" other programs by modifying
them to include a, possibly evolved, copy of itself. A program that infects
a computer by attaching itself to another program, and propagating itself
when that program is executed. A computer can become infected by files
downloaded over a network, or by the installation of new software or floppy
disks that are infected with viruses. Some viruses are only pranks, and
perform harmless actions like displaying a screen with a joke message on it. Others can destroy files or wipe out a hard drive. To avoid damage from viruses, write-protect the boot disk and other important disks, check new software or disks for viruses, and have virus protection software installed on the computer at all times. Disinfectant programs must be updated periodically because new viruses get into circulation over time. There are some virus protection programs available on the Internet for free. Knowingly spreading a computer virus is a crime punishable by law. See also Trojan horse and worm.
