DETAILS ABOUT MACRO VIRUS
Since the computer began to be popular and used in almost any field and for any task, viruses have accompanied its growth and expansion. And although in those early moments it was more of a question of rebelling against the system, the scenario has changed today, with the development of viruses being a most profitable activity.
If you want to learn more about the dangers of macro viruses, do not hesitate to carefully read all the content of this post, where you will find everything you need to avoid having problems with this type of virus so common in offices.
What are macro viruses and how to stay safe?
Before starting it is necessary to remember that macros are small programs that include instructions and commands that are used to infect popular apps, such as office suites such as Microsoft Office, most commonly in Word or Excel, to automate or make easier a tasks that would otherwise be much more complex to perform.
These macros are used by virus developers to include code that, when executed, opens a door to the attacker that is used to steal information or infect through expansion to other files on the system for various purposes, always illegal, such as It could not be otherwise.
One of the simplest ways to get infected with a virus through a macro is to receive a document, which can be an Excel or Word or any other that uses macros as part of its work, that contains an infected macro, a very common situation today in day. By opening it and executing the macro, which can be disguised as anything else, apparently harmless, we are unleashing a series of events that can even end in the hijacking of our computer.
This is because hidden among the harmless instructions that the macro contains, there is also code that will allow the cybercriminal to download malware or viruses to our PC, and already in this instance, attack us or attack our contact list, for example.
How to beware of macro viruses?
At this point, and to provide us with the most robust security framework possible, the first thing we have to remember is everything we have learned about viruses and how they attack us. In the fight against viruses, our intelligence and common sense are 100% important.
This means that we are the first line of defense, or last, depending on how it is understood, and we should not fully trust the characteristics of any antivirus software, since they can be wrong.
For example, in the case of receiving an attached file from someone we do not know, the best we can do is open it in "Read Only" mode, since this mode will not allow the execution of macros or any other item attached to the document.
If the document is accompanied by a message that asks us to enable macros, the first thing we have to do is check that this request is well founded. If the document in question is only text, or numbers in Excel columns, it is most likely that we are being tricked into enabling macros and through them making us fall into a death trap.
In any case, never, under any circumstances, should open documents from sources that we do not know, even less that arouse the slightest suspicion. If we receive an email notifying us or informing us of something that we did not request or that we have no idea what it is about, it goes without saying that that attached message should never be opened.
How to stay safe from macro viruses?
The first slogan that we must remember to stay safe from malware is to use common sense. If we receive an email informing us that we already have a package available, but we do not expect one, it is obvious that it is a trap, and therefore we should not open it.
In the case of macros, if we open a file, and we are shown the notification to activate the macros, the first thing we have to think about is whether it is necessary for the document to contain macros. In the case that the document only contains text and some images, then there is no need for macros, therefore it is a hoax.
It can also happen that we receive an email from a trusted contact, and that it is infected with malware. Being from a known contact, we will most likely open it without thinking twice, but this can be a fatal mistake.
The point is that our contact may already be infected and we may be the victims that were available in their contact list. This means that we should not open any attachment without first checking that it is clean. Fortunately, realizing this is easy, since a document infected with a virus macro can be recognized since they generally do not have a message in the body of the email.
If this is the case, it is best to check with our contact to verify that it was who sent us the message. If you haven't had any input on the subject, then the only smart option is to delete the email with its content.
How to fight macro viruses?
One of the first things that are usually advised to fight macro viruses is to use a modern and up-to-date antivirus, which will prevent malware from being downloaded to our PC or information leaking outside our computer.
However, the best we can do is be careful and follow a series of tips until they are well assimilated. A good example of this is when opening a Word document that we think might harbor macro viruses inside it, hold down the "Shift" key, which will prevent macros from running.
Delete macro virus
Unfortunately, if we are users who do not take security very seriously, becoming infected with some type of macro virus is very simple, and worst of all is that the antivirus that we have installed on our PC is not of great help to us. The only thing they can do is help us clean up in the event that the macro virus downloads other threats or sends or receives data to or from our computer. That is why we must always make a backup copy of our most important data, since in the event of a macro virus infection that we cannot control, we can always format the computer so that everything returns to normal.
