A Trojan is a malicious program. It is created and distributed by humans. If it is present on a computer or cell phone, the device slows down and the files present on it are damaged. Therefore, it is important to know how to remove the Trojan.
PC software
To remove the Trojan from your computer yourself, you should use special programs, for example:
- Trojan Remover. Modern software that removes worms, trojans, spyware. It can be used in demo mode for free for 30 days. Trojan Remover is suitable for all Windows versions. It has an English interface and weighs only 16.6 MB. You can download it;
- SUPERAntiSpyware. You can use this free program. It is also suitable for any version of the Windows operating system. It is distinguished by a simple interface in Russian and a quick PC scan for Trojans. You can download it;
- Spyware Terminator. This program is freely available. It has a Russian interface. With its help, you can perform a full computer scan and destroy Trojans within a few minutes. You can download the Spyware Terminator software on the manufacturer's official website.
Phone software
Mobile phones are often infected with Trojans. For such devices, their own programs have been developed that remove malware. Here is a list of the most popular ones:
- Avast Mobile Security. Such a program is great for Android. It will quickly scan your phone and remove all Trojans. In the future, it will provide reliable protection against any malware. You can download Avast Mobile Security;
- Doctor Web. With this program, you can quickly get rid of Trojans and prevent them from reappearing. It is suitable for devices running on Windows Mobile operating system. You can download it;
- NOD32 Mobile. This antivirus program will remove all trojans, worms and malware from your phone. Then it will protect the device from virus infection. NOD32 Mobile runs on a variety of operating systems, including Android, Windows, Symbian. To download it, you should go
A Trojan horse (or simply "Trojan") is known as a malicious program that performs actions on a device without the user's knowledge. If it is on the device, it must be removed (it is not known where and how it will spoil). Trojan and normal virus are different from each other. So the virus can self-replicate, i.e. move around the file system or from computer to computer.
But the Trojan program (remember the wooden horse in the ancient Troy) looks like an ordinary legal product, but only a completely different one is embedded inside it, for example, the purpose of which is to steal your passwords, spy on you (to monitor what you are doing on the device, etc.) In general, such muck must be removed.
By the way, there is no 100% way to detect and remove such programs. there are many modifications of them.
How does the Trojan get into the phone?
It can get to any device (computer, tablet, smartphone, etc.). It hits the android different ways, for example, when downloading applications from the Internet (often download all sorts of hacker hacked programs - you will probably find them there and pick them up). When exchanging files using Bluetooth, the Trojan can infiltrate the phone. You can also infect an android by sending SMS or MMS. Simply put, with any download of information to the device, you can add such a dirty trick.
Almost all Trojans disguise themselves as useful applications, so there is a greater chance that the user will download it. It can be created under the name of an existing application, even perform some functions, but at the same time, malicious programs on the computer will grow rapidly.
How to identify a Trojan?
You can detect the presence of a Trojan yourself. You may notice changes in your phone, most likely this will mean the appearance of a Trojan. The phone may run slower, and the charging may run out faster than usual. Some programs may be uninstalled, others may be downloaded. There are times when the user does not touch his phone and the functions work by themselves. This is a sure sign that you have malicious code.
A video about what such a thing does on a computer and, accordingly, on a smartphone.
How do I remove the Trojan?
- If you have a computer, you can use it to remove the Trojan. You need to connect your phone to your computer via USB. Then, through antiviruses, you should scan the phone and find the Trojan. There are a lot of antivirus programs, any can be downloaded on the Internet. After scanning, the antivirus program will remove the Trojan. After getting rid of the virus, the phone can be disconnected from the computer. Most likely, all settings will be reset, so it is better to copy the files somewhere in advance so as not to lose them.
- You can remove the Trojan even without having a computer. To do this, you need to download the Kaspersky Mobile Security or Doctor Web application. Run it and it will find and remove malicious code.
How to protect your phone from Trojan horses?
To prevent the Trojan from entering the phone, you need to download antivirus software. There are a lot of them, you can always choose something to your liking. The most common ones are Kaspersky Mobile Security, Doctor Web, Avast, Symantec. Searching the Internet, you will find many other analogs, but the most popular tend to protect better. Before downloading, it is better to look at the reviews to be sure that the program is needed.
Installation antivirus software usual. We go to Google Play. In the search engine we register dr web.
And click on the corresponding icon. If you don't like Doctor Web, you can choose Avast (a matter of taste).
Here's another video of what these viruses do.
Well, did you want to install an antivirus program on your phone?
Unfortunately, we have to admit that practically every user of computer systems based on Windows OS has come across in one way or another such a concept as a Trojan virus. What it is, very many users have very little idea. Moreover, almost no one has any idea how to remove the Trojan virus entirely. Let's find out what can be done in this case.
What is a Trojan Virus?
Let's start with the most basic. The owner of any computer or mobile device must clearly understand that if the device runs under the operating system, it means that it is not immune from the penetration of extraneous threats. Of course, this applies to systems like Mac OS X or Linux (generally, UNIX-like systems) to a very small extent, because viruses of this type are simply not designed to run in them, and the systems themselves have a sufficiently strong and impenetrable security system in all respects.
Windows or Android-based mobile platforms are another matter. There are so many gaps that a Trojan virus can perceive a mobile device or computer, so to speak, as a "native" application that does not pose a threat in terms of execution.
In fact, as is already clear from the name of the threat, the virus was originally associated with the ancient Greek legend of the conquest of Troy, when a huge wooden horse was presented to the inhabitants of the city as a sign of a truce. That's just the trouble - the soldiers were hiding in it, who at night opened the gates to the enemy army.
How does the virus get into the system?
The Trojan virus works in a similar way. This malicious program enters a computer or smartphone under the guise of a standard application (even with a meaningless name), pictures or something else (even from popular social networks), and when the time comes, it is activated.
Penetration can be associated primarily with Internet access, since it is usually not saved on removable media, although there are such cases. But when you visit any sites with a dubious reputation or even known, but infected with viruses, the problem of how to remove the Trojan virus becomes almost insoluble. Who hasn't encountered a problem when, when downloading content from VK, the antivirus starts, to put it mildly, "spitting"?
As you know, almost any virus code today is self-copying, which only means that if the main executable file is deleted, its copy will still remain in the system and will continue its malicious activity.
Virus damage
Naturally, when looking for an answer to the question of how to remove a Trojan virus from the system, one should take into account both the harm it does to it and the possible consequences, because if it is manually removed incorrectly, it can "hook" a bunch of system files (infected with it), which will lead to the complete inoperability of the "operating system" and the device on which it is installed.
In general, in terms of knowledge about computer viruses, Trojans, or, as they are also called, "computer worms", are not aimed at deleting information or destabilizing the entire system as a whole.
Here, rather, the action is aimed at gaining access to a computer terminal, user account, system management or theft of confidential information. Less common are options for interfering with the operation of certain applications, including even standard antiviruses and Windows security tools. Unfortunately, there are practically no them in Android.
Therefore, even the problem of how to remove the Trojan virus from Android is solved only with the use of third-party programs and applications created by other developers. But that's not the point.
Standard means of dealing with the threat
Many, so to speak, novice hackers, as they like to call themselves, often wonder how to create Trojans viruses. For obvious reasons, we will not consider this, although even with minimal knowledge of any programming language (even an entry-level one), this is not so difficult to do. Let's better turn to how you can deal with such threats and the consequences of their activities.
For Windows, on a "clean system" just installed, there is practically no tool available, except a built-in firewall (aka firewall). Unfortunately, this "wall" is capable of blocking the non-penetration of viruses or the installation of their components in the background, namely the installation processes launched by the user (manually or when visiting any Internet resources). It is probably already clear that the question of how to remove the Trojan virus cannot be solved by the system's own means. Here you will have to use not only standard antiviruses, but also independent system scanning tools.
How to remove Trojan virus on Windows?
Trojans are so deeply rooted in "operating systems" like Windows that sometimes even installed antiviruses do not help. However, the standard removal tool malware and codes are considered to be exactly them. Every user should have such a package at their disposal.
What exactly it will be - Kaspersky, NOD or some kind of free package - everyone decides for himself. It is worth noting here that paid or shareware packages have much more ability to detect this type of threat. This is especially true for products like Smart Security or Internet Security, which monitor the penetration of threats in real time.
For the most part, free antiviruses simply pass by Trojans, considering them, say, some kind of unofficial additions to installed software products. Nevertheless, if the threat nevertheless entered the system, removing the Trojan virus with any powerful antivirus will not be difficult. In this case, however, the user must specify exactly what actions will be performed: either the removal of the virus itself (which is very rare), or the treatment of infected files, or their complete removal. This is where we come to the conclusion that improper removal or use of the wrong antivirus package can lead to a complete "crash" of the system.
Consequences of incomplete virus removal
It goes without saying that any free scanner by signature is able to determine the original file of the virus that entered the computer or phone. As a rule, all Trojans, for example, on Windows, have Win32, Worm32 or Trojan.Win32 in their hidden name (this is how the antivirus itself recognizes it).
As expected, the file path will be specified. However, having removed it using a primitive package or manually, the user completely forgets that copies of it can remain in the system under different names and with different extensions. Moreover, the Trojan virus is able to create its own entries and keys in the system registry, as well as in the boot sector, which only leads to the fact that the malicious code is activated again and again at startup.
Remove threats from Android
Android operating systems in different versions and assemblies are also not immune from the influence of "computer worms". The built-in security system in the form of the so-called McAfee “antivirus” is only capable of blocking devices if they are stolen, lost, or if an incorrect PIN is entered.
The question of how to remove the Trojan virus from "Android" torments all owners of devices based on this "operating system". Since your own funds do not help, then you need to use third-party software products. Here one of the leaders, and the most powerful and demanded, can be called the unique 360 \u200b\u200bSecurity program, which appeared relatively recently in the same Google Play and Android Market.
How to remove Trojan virus from Android phone on board using this app? It's simple. First, a scan is set, after which the program displays not only a list of found threats or virus-related files, but also absolutely safely cleans infected files from infection. The statistics speaks for itself: it is not in vain that the number of downloads on the same “Market” has exceeded 100 million. In addition, the application itself is completely free. True, there is one nuance: after installation, it always hangs in RAM, and its icon is present in the top notification bar (so to speak, the Android system tray is like Windows). But agree, what is more important - security or a little more load on system resources?
If all else fails
For Windows systems, there is perhaps the most effective way to get rid of these types of threats (especially if they have already leaked into the boot sector or system memory).
A Trojan virus can be recognized and removed even before the OS itself boots by using utilities such as Rescue Disc. They are launched either from a flash drive or from an optical disc such as CD / DVD, have a graphical interface and remove even those threats that the usual installed by default antivirus can miss, for example, due to the blocking of its work by the same virus.
As practice shows, this method is the most effective, since in this case the threat is eliminated not only in the form of infected objects, but also in terms of deactivating the carrier itself, which, as mentioned above, can even be located in the boot sector.
Unfortunately, such utilities are not provided for systems like Android. Even the so-called hard-reset (forced reboot) will not help here. So you have to be content with what you have.
Outcome
If we draw some conclusions regarding the virus itself and methods of dealing with it, it is worth saying that it is more a spy than a file or system shredder. However, if someone stores passwords or access codes to bank details on a computer or phone (even encrypted using AES 128 or 256 algorithms), be sure the virus will not let them through. And he breaks such codes (although it is argued that this is impossible) simply "with a bang." The usual keylogger works. So be careful!
