All About Computer Viruses

Computer viruses are a PC owner's worst nightmare. There are many different viruses and some are more harmful than others, but they all have one thing in common: they easily spread from computer to computer, and once your system has been infected, you need to get rid of it to reduce any risks.

Basically, it's a computer program and it's often hidden in a file that moves from PC to PC. They can disguise themselves as innocent documents or other file types and install themselves on your system once the file is opened.

When it ends up on your system, it can...

  • take up disk space and influence your system's performance
  • and worse, create havoc inside your PC by deleting and/or “stealing” sensitive data.

In the early days of computing all malicious software was called a virus. Nowadays computer viruses represent only a small subset of malicious software (also known as malware) but many people speak of computer viruses if they found any kind of malware on their computer.

Antivirus software is the most common tool to fight infection and is in most cases, very effective. But beware, for some types of malware, such as rootkits, you might need specialized applications.

It is often stated that computer viruses are a “Windows problem”. Virus authors want their program to be effective as possible and thus it makes sense to them to write a malicious software program especially for Microsoft Windows, which is the world's most popular operating system.

However, other operating systems such as Apple's Mac OS X and Linux are not immune to viruses. They can become the carrier of malware and distribute it to Windows systems they communicate with. Programmers of malware have also started to write viruses for Mac OS X and GNU / Linux. Today is also recommended antivirus software to buy for Mac OS X.
