When generally speaking about viruses; it is usually generalized with respect to all those things that in one way or another threaten our devices in a computerized way. These viruses however, we can classify them by many names which will help us to better define their lethality within our operating systems.
From worms, Trojans, up software spy each, and although these threats in different ways are lethal to our computers.
Each of these threats has different characteristics of its own, which also use different techniques for the sole purpose of infecting a user. Many of these techniques are executed without the user being aware of said action. However, on the web we can find various special viruses, called “direct access viruses”.
Which combines a worm and a Trojan, which when it infects the computer, and automatically begins to hide all the computer icons, in addition to the folders that the user has within his system and begins to change them for various shortcuts. These entrances also have the same appearance as the originals.
In this way, when the user wants to execute any of these accesses in a normal way, it executes a threat, which will begin to duplicate itself within the device, also seeking to infect other computers.
In general, this type of virus is distributed over the Internet, but something that not everyone knows is that one of the most common forms of infection is via USB memory sticks or external hard drives.
In this post we will help you to identify and eliminate all these viruses and likewise, that you begin with a thorough cleaning of your devices, so that this situation does not repeat itself again and thus you will protect your devices from these malicious agents.
How to remove a virus from a computer
Although this type of virus is so basic that any security software that is properly updated could detect it; it is something that could present a serious problem in the long run. In addition, it is important that it be eliminated in time so that it does not damage sectors of our PC and that this becomes irreplaceable.
However, when a computer is seriously infected; the situation is usually complicated due to the large number of copies of the same virus, which will make it difficult to eliminate it directly.
To begin to disable the threat, one of the simplest steps is to eliminate all those shortcuts that we observe on our PC. This in order to prevent the malware from replicating itself. For this action, we only have to connect to the disk or, failing that, to the memory that is infected and; With the help of a CMD window , we will start executing the following commands:
- E: (or failing that the letter where the infected memory is mounted).
- del * .lnk (with this we will begin to eliminate all those files that are created by the virus and that are likewise a virus).
- attrib -s -r -h / s / d *. * (we will use this to apply the different standard attributes to all those original files and return them to their original place).
However, we must be careful, because if our PC is infected, when we proceed to connect an external memory, it will be infected again.
For this reason and in order to finish completely with the threat, can rely on applications like USBFix which is intended solely to help disinfect different disks external via USB, it can run equally within an internal hard drive for the sole purpose of completely removing the threat from your computer.
Try to remove all your files and format
Once you can get a little more clarity regarding your files and you can see a little further with all the files, it is important that you enter your USB memory and start cleaning. What we recommend is that you copy and paste all the files and after that format and re-enter them.
