Learning What Are Trojan, Worms And Viruses And The Right Way To Prevent It Using Computer Security

Malicious software (malware) is a program designed to damage computer systems

. Viruses and spyware (spyware) are the two main types of parasites which may be installed on a computer to cause damage or to remove personal information. Viruses are known for their destructive activity and their ability to spread rapidly by email and networks (worm or email worm). Spyware are not all illegal and dangerous, but their common point is to use the Internet connection to discreetly communicate with the outside. Some are content to watch our actions of users while others open pop-ups advertising (adware).More aggressive versions have emerged with the appearance of a new form of crime related to trading activities on the network. The dialers can take over a modem to dial premium rate numbers, but are certainly the most dangerous keylogger designed to capture passwords entered in forms.

The year 2007 saw a sharp increase in infections with the new generation of malware found in web pages. These applications use browser vulnerabilities to install on the hard drive and allow remote takeover. The Firefox browser contains fewer security holes than Internet Explorer. Increasingly sophisticated and undetectable malware called "rootkit" are able to settle in the heart of the system by usurping the rights administrators. They can hide their presence, away from system calls and hide the connections they use. To control the integrity of your system, use a utility of the family "IDS / IPS".

To secure your computer, install anti-virus software and keep it updated. Add a firewall software that will notify you of any attempt to use inbound and outbound anomalous your Internet connection. Make the critical updates for your operating system. If you use the Windows operating system from Microsoft, the critical updates can be automated regardless of the version used.

The virus is never completely up to date, it is also recommended to follow some basic rules that will prevent contamination of your computer.

Do not install software of unknown origin. Prefer free software whose source code is known, and always download software from known platforms.

Do not open emails from unknown sources, or the e-mail attachments without having scanned with an antivirus.

Do not accept the installation of Active-X site when you offer no good reason, and usually do not surf to illegal sites. However, a legal site that was hacked may unwittingly be used to infect browsers visiting its pages.
