It represents a best-in-class solution for any Windows-based workstation. This page demonstrates its most important features and provides links to further resources.
A computer virus is a piece of software, usually malicious in nature, that is used to spread itself or other such software from computer to computer. Viruses themselves may cause system damage, loss of valuable data, or be used to install spyware, rootkits or malware onto a vulnerable system.
A key way to prevent virus infection and spreading 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.
Spyware is software that installs on a computer system and is designed to collect information about the computer user, often without their knowledge or consent. 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.
Much spyware at this time is being used by organized crime, rather than opportunistic lone individuals, as may have been the case in the past.
Rootkits are programs that install on your system, while keeping themselves, their processes, services and registry keys hidden, to stay invisible to 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. One such system is avast! antivirus 4.8.
