Malicious programs. Malicious software removal programs

So, the topic of our discussion today is malware. We learn what it's like, how they manifest themselves on computers, how to "pick up" the given infection, and also classify them all in danger. In addition, let's try to understand how it will be possible to remove them from the operating system once and for all. What programs will help us in this? Which of them best deal with the task? Now all this will be discussed.

What are

To begin with, we'll figure out what malicious programs are. After all, in most cases, depends on the treatment of the computer. Each infection has its own approach, which helps to eliminate the root of the problem.

In general, a malicious program is any application created to destroy the operating system, as well as to obtain the user's personal data. Plus, the main thing is the damage to your computer. So you have to work hard to protect yourself from this infection.

Malicious programs, as already mentioned, can be classified. And by this classification, you can determine the degree of danger of an application. Let's get acquainted with you with all types.

The first option is spam. The least dangerous, albeit unpleasant, viruses (malware) that can only be found. Usually they are aimed at showing a lot of advertising and cluttering up the CPU with their tasks. Sometimes they can steal personal data.

The second type of virus is worms. Also very "weak" infection. As a rule, gets on the computer for the purpose of own reproduction. Plus, as in the previous case, they load the processor. The consequence is the slowing down of the computer. Not critical, but still unpleasant.

The following malicious programs are Trojans. They are the most dangerous objects. They destroy the operating system, clutter the CPU of the computer, steal your personal data ... In general, the "team solyanka" of all malicious applications. They must be disposed of immediately.

The last option that can occur is spies. They are aimed at theft of personal data. Sometimes they can destroy the operating system and multiply. Not particularly dangerous for the user and the computer, but for the data it is a big threat. The system needs good and reliable protection against malicious programs to keep all documents intact.

Where to live

Well, we have already met with you with the classification, as well as the degree of danger of the whole computer infection that a modern user can face. Now it is worth to find out how the distribution of malware is happening, and where you can meet with them.

The first leader on our list is a suspicious advertisement on the World Wide Web. For example, the offer of a free download of a book that will teach you how to earn millions in 2 weeks. Sometimes it's enough just to click on a link or a banner, as the computer is already infected.

Also, viruses and malicious programs are constantly present on prohibited sites, intimate resources, torrents and so on. As in the past case, it's enough just to visit the site - and the infection will already be sitting on the computer. Most often, even the best antivirus can not help you prevent infection.

The third place is occupied by various load managers. They, as a rule, download to the computer some necessary document to you, and then install the malicious content "wagon". Try not to use such managers very often. It is better to wait a while and download the document using a browser - there is at least some protection already available. Not particularly good, but nevertheless in most cases really helping us.

Sometimes malicious programs are distributed via e-mail. You go to the unfamiliar letter sent to you - and it's ready! It's better to refrain from reading incomprehensible messages, if you do not know where it came from.

Manifestation

Well, now it's time to find out how you can understand that your computer is infected. After all, this is what helps us in time to start thinking about how to remove a malicious program from the computer. It should be noted that many "signals" users stopped paying attention. Now we will recall them, so as not to lose sight of anything.

The first obvious sign is the appearance of brakes on the computer. All this is due to the CPU load. Although this behavior may be caused by a banal system failure. Only better once again to be reinsured and check your computer for viruses.

The second signal is the appearance of new content on the computer. In this case, we are talking only about the software that you did not install. And sometimes they did not even hear about the existence of this. You should not run these, and even more so try to work in them.

Next comes the appearance of spam and advertising on the computer, as well as changing the start page of your browser. In this case, it is worth immediately sounding an alarm - because you definitely have some kind of infection. Protection from malicious programs, apparently, failed and missed a virus.

Also, a computer may experience various failures and malfunctions. There are also errors in applications, and spontaneous shutdown / reboot and a lot of this kind of "surprises". All this should be paid special attention.

How to delete: antivirus

Now it's time to find out what programs are available for removing malware. The first applications that we will get acquainted with are antiviruses. This provision is aimed at finding and removing infiltrative infection on the computer, as well as ensuring reliable protection of the operating system.

Frankly, there are a lot of antivirus programs. Any user can set himself the one who likes him specifically. There is no fundamental difference in them. Nevertheless, the best way to cope with their work is Dr.Web, Nod32, Avast. As many users have noted, it is these antiviruses that quickly detect the infection, and then delete it, inflicting minimum harm to the operating system.

Anti-spyware

The second ally in the fight against viruses is an antispyware program. Unlike antivirus, the action of such content is aimed at the detection and removal of computer viruses-spies. They will not find any Trojans. Usually, they are used after the antivirus on the computer.

Programs for removing malware are very extensive. Nevertheless, among them one can single out one leader who perfectly searches and eliminates spies in the operating system. This is SpyHunter.

It's enough just to download, install and activate the latest version of this security. After that, run the application, configure the scan and run it. Then delete all that was found (for this, a special button will appear). That's all. The application is freely available, and also has a simple and intuitive interface.

For the registry

Sometimes viruses and spyware are registered in the registry of your computer. This greatly complicates the healing process. What can be done in this situation?

Of course, you can clean the registry of the virus yourself. But it's best to use special utilities for this purpose. For example, CCleaner. With its help, you will easily scan the computer, and then clean all the "extra" and dangerous data in the system registry.

To do this, download, install, run and configure the program. After running on the left side of the screen, check all the hard disk partitions, as well as browsers, by ticking. After that, click on "analysis", and then on "clean up". That's all. Quite easy and simple. Even a novice user can cope with this application.

Uninstall programs

Of course, everything that was described above is a great way to eliminate all the viruses hanging over the system. True, they should not be limited. Let's find out what other steps should be taken if you suddenly have any computer infection in the system.

Of course, this is the removal of all unnecessary programs on the computer. With all this, special attention should be paid to the content that appeared after infection of the system. To get rid of it you have to use "Control Panel". There, find "Add / Remove Programs", and then wait for the downloads of the list of all installed content. Next - find something that was established "by itself," select the line and click on "delete." That's all.

We finish the fight

Today we talked to you about malicious programs, classified and understood what signs distinguish a healthy computer from an infected one. In addition, we got acquainted with the most popular programs for removing computer infection.

In general, all the healing of operating systems is reduced to the following algorithm: all installed applications (third-party) are deleted, the system is checked using an antivirus, then it is scanned with antispyware, then the registry is cleaned. Everything comes to an end with a simple reboot of the computer. Thus, all problems are solved.
