How to choose an antivirus?



How to choose an antivirus? As the author of the article is a system administrator, one of his official duties - perhaps the most important! - Is the protection of both individual PCs and corporate local area network as a whole from various internal and external threats.

Long-term daily "communication" with viruses, spyware and other digital evil spirits can more or less objectively evaluate the effectiveness of remedies (Please note that the assessment author of the article antivirus entirely based on personal experience and may differ from generally accepted!).

What motivates PC users the choice of programs? As a rule, experience: or their, or someone else. Every user - their passions, their "gentlemanly" set of software.

Antivirus - these are the same program, but the program is very important because they determine whether we work on your PC safe and effective, will ensure the integrity and safety is most precious - our information.

Basic requirements for antivirus:
- Producer (whether it is credible global brand in its field);
- The composition of a software package (a good anti-virus, as a minimum, include:
1) antivirus monitor, constantly "monitoryaschy" memory and all files, folders and drives that are accessed by the user;
2) module, which monitors the integrity of the anti-virus software package;
3) anti-virus scanner that runs on demand;
4) a regularly updated set of antivirus databases;
5) module to update antivirus databases;
6) a module for creating emergency boot disks, allowing for the need to test the system in the so-called "clean" environment;
7) Firewall (also called a firewall, or firewall);
- Performance (anti-virus should provide maximum protection and it does not "impede" system);
- Frequency of virus definition updates;
- The number of viruses and other malicious software that can identify and block antivirus;
- Frequency of updates;
- The possibility of blocking unknown threats (genetic heuristic checking suspicious code and behavior analysis programs);
- Accessible interface and easy setup;
- Availability of localized versions of the program (for Russia - russified);
- The price of the product.

The world market for antivirus programs are very extensive, there are plenty to choose from (there is no monopoly!).

To begin with, what with all due respect to Igor Danilov, I can not recommend Dr.Web Anti-virus for wide application. Until now, young people excited about this anti-virus. The reason for such popularity is clear: this antivirus is less than other "loads" system. But while he is working less efficiently?

Many of the young "aytishniki, fans Dr.Web, and say they Antivirus Panda, Norton, Kaspersky - they are very" loaded "system! But what is very "loaded"?

First, any anti-virus after installing - despite advertising "set and forget!" - Need to configure a specific computer and a particular user, for installation by default do not allow effective use of antivirus!
Secondly, RAM 1 GB or more is not surprise anyone, and if a gigabyte of RAM Antivirus uses even 100 megabytes - that it's worth it!

Thirdly, to run demanding applications (which are the most "voracious" - "child" programs and games such as video editing), downloaded the processor at 100% and sometimes require more than 1 GB of RAM (and sometimes even swap file) - is not that much "Georgia" system?

Fourthly, when dealing with the same video editor (when you are disconnected from the network and there is no threat to PC), who prevents you temporarily disable the antivirus?

Fifthly, and you know how many services (necessary and unnecessary) is loaded by default with the operating system, gobbling up CPU time and memory?

Recently gaining momentum antivirus NOD32. A good antivirus, but it is still evolving.

Of the greatest of multiple anti-virus - for performance - personally I like three: Panda, Norton, Kaspersky Anti-Virus.
Compare the number of identified threats (at 29.10.07): Panda - 1.686.394, Kaspersky Anti-Virus - 448,438.
