It is quite possible you are flooded on a daily basis with spam mail and unwanted pop-ups which advertise the most recent in spy-ware and antivirus protection. As un-amusing and counterintuitive as it might be, competition as well as the effective differences between competing antivirus application developers is so tight, that even the manufactures of antivirus programs are willing to exploit your computers weaknesses to promote their solutions.
The sheer size and efficiency in the internet as well its billion-plus users makes new computer viruses more dangerous and virulent than in the past. Viruses can literally spread around the globe in just minutes, effecting thousands of unprotected and unprepared users and businesses virtually instantly and simultaneously. The need for antivirus protection is of paramount concern for nearly all PC users.
First Off: What exactly is a Computer Virus? To be considered a true computer Virus, a program needs the cabability to replicate itself and trigger its activity at specified events. A personal computer virus is just one of three types of programs referred to as “maliceware”. “Maliceware” are applications made to damage, delete or steal your data, hijack your personal computer and even damage or destroy your computers hardware. The 3 varieties of “maliceware” you have to concern yourself with are Viruses, Trojans and Worms. Most antivirus programs are designed to detect and defend your PC from all three threats.
What Does an Antivirus Program Do?
Antivirus programs take two common methods to recognize threats to your computer.
1. Signature Detection: Via Signature Detection an antivirus application scans your personal computer, drives and storage devices for files that have a code it recognizes as a virus variant.
2. Activity: An antivirus application will monitor the activity on your personal computer for suspicious behaviors i.e. modification of system files or folders and unauthorized connections to the internet to name two.
Signature detection generally necessitates the manufacturer of an antivirus application to have a copy of any specific virus and after that reverse-engineer it to obtain markers highly relevant to its programming. These markers are then loaded into your antivirus software via updates. Signature detection is a sound methodology for detecting and protecting against computer viruses, however it could be rendered useless when confronted with a computer virus for which is has no definition.
Antivirus applications that scan for potential computer virus activity can be more useful at detecting the newest threats as opposed to those reliant on signature detection. It is essential to note that because many applications perform the same activities as being a virus – writing and changing system files for example – an individual can quickly become inundated with numerous and unnecessary warnings by antivirus applications that utilize this technique for detection.
Most of today’s “solid” antivirus programs utilize a combination of both signature detection and virus activity to safeguard your pc against threats.
How to Choose the Antivirus Program that is Right for You.
By trying surfing the web for insight into what is the best antivirus program or manufacturer, you will easily discover yourself neck deep in a sea of advertisements which profess themselves to be legitimate and impartial evaluators from the available programs.

How in danger have you been?
Wondering this query is probably the first and most essential step toward choosing what level of protection you require, and how much cash you are able to spend, on Antivirus protection. Risk generally equates to your computers exposure to outside applications, files or connections. If you decide to manage a computer that would never come into exposure to any program or file not manufactured by way of a secure source, then you have virtually no requirement for an Antivirus application. In other words, in the event you never want to connect your computer to the net, download files along with it or upload “in danger” files externally data sources, you should have no need for Antivirus software.
In case you are a friendly user who perhaps connects to the internet on occasion through a temporary or dial up connection and only download or upload files and programs from reasonably secure sources, your need for an antivirus program is apparent, however, your risk could be minimal. In cases like this the types and selection of protective applications may be kept as low as possible; a fundamental antivirus program designed to regularly scan your hard disk drive for infections should offer you the safety that you require.

Are you Purchasing for Business or Home?
Antivirus software manufactured for business and home could be two totally different applications in cost and effectiveness. Home versions generally are less expensive and come with fewer options than business based antivirus programs. Usually the home user does not require the added functionality included in business versions and therefore, I might not advise that a property user invest in an antivirus solution created for business.
Good antivirus software intended for business is centered on security, both from external and internal threats, in addition to simplicity of maintenance. Most corporate versions of antivirus applications allow for a central reason for control of entire networks. Protection could be divided between internet or application servers and individual PCs. New software updates are usually “pushed” coming from a central application server through the entire network, permitting simplicity and assure-ity of the network’s protection. Most times, corporate versions of antivirus applications do not allow individual users within a network to help make changes to their protection settings; this is of key importance when contemplating overall network security and stability.
As being a business purchasing a corporate class antivirus suite, it is important that your protection extends to every person user that can access your network. Exchange/mail and internet server protection is essential, in addition to protection for mission-critical file and application servers. It is a good principle for this managers within corporate environments to imagine that all their users is going to do everything within their power to infect corporate equipment with viruses and threats. Though this most definitely is not really true, assuming that users learn how to protect themselves or their corporate computer environment from infection is in most cases professional suicide for your IT manger in control.
Antivirus software for company is generally loaded with more options than software developed for home, and thus is often times far more expensive on a whole. Usually business antivirus programs come as a server akhoky application. Clients, or additional licenses, are purchased for every computer or user that connects for the antivirus server.
Regarding the Antivirus Program Itself: Determining the actual quality and effectiveness of the antivirus program can occasionally fall to how many times the producer releases updates for the program. New viruses are brought to the web of all certainly an everyday, if not hourly basis. The best antivirus manufacturers release updates every day and frequently offer updates with their programs on the real-time, when necessary basis. The capability to have an antivirus software manufacturer to release constant, and relevant, updates with their programs should be of great concern to the user. Without having the latest updates can almost be as dangerous as having no protection at all.
