When we refer to office automation jobs and their corresponding files, we are talking about text files, spreadsheets, PDF, etc. These are elements that we use in a multitude of environments and types of work, both on mobile phones and on desktop computers. Therefore, we must ensure that they are free of viruses or other types of malicious code .
In fact, in these same lines we want to focus on one of the most used office formats in the world, we refer to Adobe PDFs . Over the years, this type of file has spread to a multitude of fields and modes of use. So right now we use a PDF to save documentation, sign legal documents, manage invoices and estimates, etc.
Considering that these are items that we generally find, share and download from the internet or send by mail, security here is key. One of the most common programs when reading this specific content is Acrobat Reader DC. This is an Adobe application that many of you probably already know as it is very often used as a default PDF reader. But in order to use this tool with total security, it offers us a series of functions related to this section that we should take a look at.
These will help us to be able to work with these files that we are commenting on without the risk that some type of malware infects our computer. First of all, we must know that this is an application that we can download for free from here.
Enable protected mode
As we say, this is an application that has various functions related to security to avoid problems in this regard. The first thing we are going to do is start the program and go to the Edit / Preferences menu of its main interface. In the left panel we will find various categories that will help us to configure Acrobat Reader DC to the maximum.
The first thing we are going to do in this sense is to activate the protected mode so that it starts working as soon as the program starts . For this we access in the category of Advanced Security. At the top of the window we find a box that allows us to enable this protected mode that we are talking about.
Configure protected view of PDFs
In the event that we have activated the protected mode function that we talked about earlier, now we can customize it in the protected view. This is activated on certain occasions when we load a file in PDF format in the program. In this way we prevent infected files from running here.
Say that the Adobe application allows us to activate this security function for each and every PDF that we open, or only for potentially dangerous ones.
Use external security settings in Acrobat Reader
For those who want to take the use of this program safely to the highest level, it proposes us to use already predefined configurations. With this, we want to tell you that we have the possibility of importing a secure configuration file and loading it into Acrobat Reader.
For this that we tell you, as before, we must go to the application preferences window. In this case we go to the security section where we will have the possibility of importing the file that we are commenting on. Similarly, from here we can load the security configuration from a remote server and customize the use of secure certificates.
