A computer virus is very similar. Designed to relentlessly replicate, computer viruses infect your programs and files, alter the way your computer operates or stop it from working altogether. It’s estimated that the Conficker virus infected more than 10 million computers in 2009. Tens of thousands of computer viruses now operate over the Internet, and new computer viruses are discovered every day.
How does a computer virus find me?

    Malicious software, referred to as malware, can contain a variety of threats, from data loss to system failures. There are several types of worms, viruses, Trojan horses and spyware, which can be delivered in a variety of ways. Computer viruses are a type of software or executable file that attaches itself to other programs to be uses. Viruses can cause system failures, rewrite hard drives, or destroy files and programs.

    • A COMPUTER VIRUS is a computer program that attaches itself to another computer program (known as the host program) and attempts to spread itself to other computers when files are exchanged. • Creating and disseminating computer viruses is one of the most widespread types of cybercrimes. Tens of thousands of new viruses or modified versions of old viruses are released each year. • Viruses normally attempt to hide within the code of a host program to avoid detection. Viruses, by definition, have a method to spread themselves. • Any computing device such as a smartphone, notebook, netbook, or iPad can be infected with a virus. Even your car, which now contains embedded computer systems, could catch a virus, especially if it connects to the Internet for software updates.…

    A computer virus attaches itself to a program or file enabling it to spread from one computer to another, leaving infections as it travels. Like a human virus, a computer virus can range in severity: some may cause only mildly annoying effects while others can damage your hardware, software or files. Almost all viruses are attached to an executable file, which means the virus may exist on your computer but it actually cannot infect your computer unless you run or open the malicious program. It is important to note that a virus cannot be spread without a human action, (such as running an infected program) to keep it going.…

    Malware, short for malicious (or malevolent) software, is software used or created by attackers to disrupt computer operation, gather sensitive information, or gain access to private computer systems. It can appear in the form of code, scripts, active content, and other software. 'Malware' is a general term used to refer to a variety of forms of hostile or intrusive software. This malware will operate invisibly, often without displaying itself in your Task Manager. To top it off, malware usually refuses to be uninstalled through your control panel, and requires special tools to delete them from your drive. Yes, this is a direct cousin to viruses, but with a broader portfolio of wicked intentions.…

    Computer viruses can be a nightmare. Some can wipe out the information on a hard drive, tie up traffic on a computer network for hours, turn an innocent machine into a zombie and replicate and send themselves to other computers.

But the concern is understandable -- according to Consumer Reports, computer viruses helped contribute to $8.5 billion in consumer losses in 2008 [source: MarketWatch].
