Antivirus programs

When working with a computer, as well as when working with any other device, you must observe certain security provisions. We will not tell mature people about elementary rules of behavior with electricity. We will talk about other dangers, which every computer owner knows. The word will be about computer viruses, but more precisely about software tools to combat them.

Modern anti-virus programs are powerful complexes, in which several modules enter. Therefore, when choosing a program, care must be taken to the composition of the modules included in it.

Comfort of work with antivirus is another important characteristic, which should be noted. Undoubted advantage is allowed to call Russian-speaking teams also the names of menu items. A small file size of the program is just one of its advantages. It is much more important to pay attention to the exactingness of the anti-virus to the resources of the computer. After all, the module "watchman" is permanently in the computer's memory, eating up a share of resources. It is important that the presence of the watchman is not felt by the user during everyday work. So why do you need an antivirus, which in a couple of times reduces the speed of work of other programs?

The ability to test a product in labor is very important when choosing software. As the situation is possible, that on some computer also to the operating system the program behaves in an unexpected way.

Another important factor is the speed of the antivirus developer's reaction to the appearance of new viruses, but as a result - timely update of the anti-virus database.

Kaspersky Lab

Developer: Kaspersky Lab
Developer's site: www.kaspersky.com
The cost of the annual license: 69 US dollars (for the version of Personal Pro)
Distribution size: 14.1 MB

One of the leaders in the anti-virus software market, last year introduced a new version of its product Kaspersky Anti-Virus Personal 5.0. According to the developers themselves, one of the first shortcomings of previous versions of this antivirus was the low speed of operation. A new version of the program demonstrates high speed of work with reduced consumption of resources.

When checking the disks, the antivirus compiles a database with information about already checked files, and later, if the attributes of these files did not change in any way, they are not checked in any way, however the program scans only new files. Previously, scanned files will be scanned again only at the user's request. This innovation also allowed to increase the speed of the program.

One of the important features of the program is an intuitive interface. All the work tools with the program are conveniently divided into three blocks, which are placed on the three tabs of the program window, these are "Protection", "Settings" also "Support". Access to control tools is implemented using the context menu of the program icon located in the system tray. From here it is allowed to enable or disable the full protection of the computer, run a disk check.

One of the first pluses of Kaspersky Anti-Virus is also users, also the developers themselves call the possibility of checking archives, even nested ones. It should be noted that this possibility is approximately unique - from the programs we examined only one more has such capabilities.

The latest version of the program can check the contents of ZIP, ARJ, RAR, CAB archives. When checking password-protected archives, the program requests this password from the user. The program supports automatic updates of virus databases. All suspicious files (then those for whom the program could not determine in any way whether it is infected or not) are located in a special section "Quarantine", in the backup storage the program writes down objects created during the anti-virus scan.

The program can be password protected. It seems that the program perfectly copes with the control of mail traffic, controlling all mail that is being sent as well.

The appearance of updates to the antivirus databases of Kaspersky Anti-Virus is one of the more rapid, sometimes download them is allowed every few hours. All this, along with a high level of virus detection, operates the program one of the best in its category.

Manufacturers of Kaspersky Anti-Virus deliver their product to users in three types of configuration. The version of Lite does not automatically update the virus databases, it does not have an e-mail checker, a scripting program also macros. Personal version does not check macros in any way. The variation in the delivery of Personal Pro includes all modules.

Plus: the ability to verify the archives, the ability to protect the program password, adapted interface.

Disadvantages: there is a certain slowness in work when using Kaspersky Anti-Virus; require additional "fine" settings, which are difficult to handle an inexperienced user.
