Internet vermin is everywhere, and any computer can easily be infected with a virus, Trojan Horse, worm, spyware, root kit blended threat, or pop-ups. The types of malicious infections we can encounter are seemingly endless — as are the types of programs available to consumers to help keep infections under control.
“When people talk about a computer virus, they generally call different types of computer viruses, like worms or Trojan horses a “virus”. While the words (Trojan, worm and virus) are often used interchangeably, they are technically not the same. However, what they have in common is that they all are malicious programs that can cause damage to your computer. They also can be found and removed by the same security program (for the purpose of this article, we also use the word virus to describe all three types of threats).”
