Threats to your computer
Viruses, spyware, rootkits and all forms of malicious software are collectively known as malware (short for malicious software); malware is also sometimes referred to as “badware”.
What is a virus?
A computer virus is a piece of software, usually malicious in nature, which is used to spread itself or other such software from computer to computer. Viruses themselves may cause system damage, loss of valuable data, or can be used to install spyware, rootkits or other malware onto a vulnerable system. A key way to prevent infection is to have an up-to-date antivirus solution installed on all computers in a network, and to make sure that all of the latest security patches for the computer operating system are installed. Users should also make sure that they can trust the source of software they are downloading from the internet, as many malware types are installed along with other legitimate-looking software.
What is spyware?
Spyware is software installed on a computer system that is designed to collect information about the computer user often without their consent or knowledge. This information may result in so-called identity theft, or theft of valuable information (such as bank or credit card details) or proprietary business data. These days, much of the current spyware is developed by organized crime rings, rather than opportunistic lone individuals and is installed by a virus or another form of malware.
What are rootkits?
Rootkits are programs that install on your system, while keeping themselves, their processes, services and registry keys hidden, to stay invisible from the user. They represent a substantial security risk on home and company networks and are notoriously difficult to find and remove. Rootkits themselves are normally deployed via another malware infection (such as a Trojan, for instance), and it is therefore highly recommended that computer users have an up-to-date antivirus / anti-spyware system installed and running on their PC.
