Defeating an electronic virus is simple. How to remove a trojan

In this article, I will discuss a topic that is worn down to holes. And it is connected with the issue of computer security. Using some simple techniques, you can become a specialist in the field of virus removal.

For example, when studying the topic of how to remove a trojan, you do not have to memorize complex terms and re-read a lot of specialized literature. The main thing is to remember what the term “Trojan virus” implies , and how to deal with it using non-standard methods of the user.

What is a trojan virus

This is malicious code that can disguise itself as the interface of any application that you are used to working with. Such viruses are usually written to steal private data, to find vulnerabilities in PC security, as well as for remote control, using weak computer security.

How to remove the Trojan beacon and other viruses using Dr.Web LiveCD.

In the context of cleaning windows from viruses, we will talk about removing viruses using a bootable CD or USB flash drive from Drweb, a well-known anti-virus company. This tool is designed to treat or remove viruses without loading windows. This is beneficial if the system is so damaged that it does not start even in diagnostic mode.

And now we will consider a number of specialized points that specify how to remove a trojan from a computer for an experienced user.

1. How to create a bootable Dr.Web LiveCD

First, from the official ftp source drweb.com, you need to download the boot image from . iso extension. The same image will be needed to create a bootable flash drive. Which of the two options is more convenient - you choose.

After copying the anti-virus software to the computer, you should write the copied to the CD-ROM. There are plenty of utilities for this purpose. For example, I am used to working with the UltraIso program.

In the window of this program, select the tools - burn the image of the CD. Then we leave all the settings as they are, and in the “image file” field, write or select the path to the boot copy of Dr.Web LiveCD and click “write”.

The first step towards the goal, how to remove the trojan, has been taken. Consider the following steps.

2. BIOS boot

The image recorded on cd needs to be launched. To do this, go to bios, in the settings such as boot setting or device priority, set the boot from the CD as the default operating system source. This must be done before removing the trojan, if windows does not start at all. We save the changes and restart the PC.

Having applied the settings correctly, you should see the Dr.Web LiveCD download window . In it, we select the first option with a graphical console and press the "Enter" key.

3. Launch the scanner

Now all work will be carried out through the console of the anti-virus scanner Drweb . By initially setting up your network, you can try to update your virus definitions. To do this, there is a large round button in the lower right corner of the application. But, as a rule, this is not necessary, because the copy you downloaded LiveCD does not expire within a week.

4. We select sections and folders for scanning. Final stage

If you press the start button, the entire computer will be scanned for viruses . Using the + and - buttons, you can specify the scan area. There is one feature here. Since it is supposed to remove the trojan under Linux, all logical partitions are attached to the temporary / win folder . When there is no partition or device in this folder, do the following:

  • In terminal mode, type: mount / dev / [logical partition name] / win / [folder name]. The mount command mounts the specified partition in the win folder . Partition numbering is from scratch.
  • The designation hda corresponds to the hard drive. Thus, for example, hda0 is the primary partition C on the hard drive, hda1 is the partition D, etc.

After scanning, the viruses found will be offered to remove or cure. Use this option for the appropriate scanner actions.
