Most IT Professional will recommend some Commercial from established companies, while others will recommend the free alternative for . For me, my answer will be fairly simple and straightforward, the best is the one that is regularly updated and upgraded. It is true, whether you are using the commercial , or the free programs out there, those programs will be useless if those programs are not regularly updated and upgraded.

So make sure you update your programs regularly, if not daily, and don’t forget to install any upgrades available from the manufacturer as soon as they are stable in their releases, for you to have the best protection.

Descriptions of Malicious Programs


This is a nice informations on the descriptions of several malicious program I got from Kaspersky website. You can view the original article here.

Malicious programs can be divided into the following groups: , viruses, Trojans, utilities and other . All of these are designed to damage the infected machine or other networked machines.

Network
This category includes programs that propagate via LANs or the Internet with the following objectives:

  • Penetrating remote machines
  • Launching copies on victim machines
  • Spreading further to new machines

use different networking systems to propagate: email, instant messaging, file-sharing (P2P), IRC channels, LANs, WANs and so forth.

Most existing spread as files in one form or another - email attachments, in ICQ or IRC messages, links to files stored on infected websites or FTP servers, files accessible via P2P networks and so on.

There are a small number of so-called fileless or packet ; these spread as network packets and directly penetrate the RAM of the victim machine, where the code is then executed.

use a variety of methods for penetrating victim machines and subsequently executing code, including:

  • Social engineering; emails that encourage recipients to open the attachment
  • Poorly configured networks; networks that leave local machines open to access from outside the network
  • Vulnerabilities in operating systems and applications

Today’s is often a composite creation: now often include functions or are able to infect exe files on the victim machine. They are no longer pure , but blended threats.

Classic Viruses
This class of malicious programs covers programs that spread copies of themselves throughout a single machine in order to:

  • Launch and/or execute this code once a user fulfills a designated action
  • Penetrate other resources within the victim machine

Unlike , viruses do not use network resources to penetrate other machines. Copies of viruses can penetrate other machines only if an infected object is accessed and the code is launched by a user on an uninfected machine. This can happen in the following ways:

  • The infects files on a network resource that other users can access
  • The infects removable storage media which are then attached to a clean machine
  • The user attaches an infected file to an email and sends it to a ‘healthy’ recipient

Viruses are sometimes carried by as additional payloads or they can themselves include backdoor or functionality which destroy data on an infected machine.

Programs
This class of includes a wide variety of programs that perform actions without the user’s knowledge or consent: collecting data and sending it to a cyber criminal, destroying or altering data with malicious intent, causing the computer to malfunction, or using a machine’s capabilities for malicious or criminal purposes, such as sending spam.

A subset of Trojans damage remote machines or networks without compromising infected machines; these are Trojans that utilize victim machines to participate in a DoS attack on a designated web site.

Utilities and other malicious programs
This diverse class includes:

  • Utilities such as constructors that can be used to create viruses, and Trojans
  • Program libraries specially developed to be used in creating
  • utilities that encrypt infected files to hide them from software
  • Jokes that interfere with normal computer function
  • Programs that deliberately misinform users about their actions in the system
  • Other programs that are designed to directly or indirectly damage local or networked machines
