It is no secret that modern security programs in the form of standard or portable antiviruses quite often behave completely unpredictably (if not to say that it is absolutely inadequate), often deleting files and folders that a user needs. And even Kaspersky Anti-Virus, widely advertised and touted by many users, is no exception. Why this happens and what methods can be used to recover any lost data, then we will try to figure it out.
Why does Kaspersky delete the necessary files?
Dealing with the reasons for this behavior of antiviruses (and not just described), we can clearly note the fact that the main reason for deleting files and placing them in quarantine is a potential threat from the object (explicit or imaginary).
Roughly speaking, almost all known antiviruses delete mostly executable program files that either interfere with the operation of the operating system or the antivirus. If everything is more or less clear with the second ones (the antivirus self-defense is triggered), then why does this apply to the applications that the user, for example, downloads for installation on a computer from the Internet?
Here the main problem is that some objects are already initially added to the anti-virus database, and it is enough for antiviruses to know their name to block or delete even without any structure check. Apparently, many noticed that very often this concerns all kinds of key generators, which are used to create activation codes or licenses when hacking paid official software (for example, files like KeyGen.exe, which may be present in unofficial distributions). Despite such tough measures on the part of the security modules, it is completely simple to get around their limitations and recover deleted objects.
Note: to prevent the antivirus from responding to such “apparent” threats, while downloading files from the Internet it is easiest to disconnect it for a while, install the required application, activate it (if required), and then bring the antivirus back to active state.
Exception setting
But back to the described antivirus. For now, we will proceed from the fact that the deletion has not yet taken place (the antivirus was disabled during the download). In principle, you can immediately add the necessary objects to the exclusion list, after which the files and folders contained in it will be ignored during the scan.
Call up the main program settings by pressing the gear button in the lower left corner, and then go to the threats and exceptions item through the advanced settings section. You can immediately uncheck the option to detect other programs besides the threats presented in the list above, and then click on the exception settings link.
By clicking the browse button, specify the path to either the file itself or the folder in which it is contained. The second option looks more interesting (albeit less secure). For example, you can specify the “Downloads” folder to ignore, after which everything that is placed in it will not be scanned by the antivirus.
Kaspersky deleted the files: how to restore them directly in the antivirus?
Now consider the situation when you did not manage to set the above settings. We assume that Kaspersky has deleted the files. How to recover lost information? It turns out that many users are completely unaware that such actions can be performed directly in the antivirus interface. Actually, deleted objects are simply placed in a special quarantined place on the hard disk, but they are not physically erased from it and stored in the created backup copy.
To restore, you will need to go to the storage section in the settings and simply select the necessary objects on the same tab and then click the restore button.
Frequently used file recovery programs
Now suppose that for some reason the operation described above failed or the threat was so obvious that the active antivirus prevented this. Again, we assume that Kaspersky has deleted the files. How to restore them if the own means of the protective module do not give the desired result?
To do this, you can use special applications, just designed to perform such actions. On the Internet, you can often come across many recommendations regarding the use of the Recuva utility. Keep in mind that in most cases it recovers only a very small percentage of deleted information. It is better to use programs containing the name Unerase or Undelete. However, if you want to achieve maximum effect, it is better to use the two most powerful utilities.
Recommended Utilities
We are, of course, talking about free programs for recovering deleted R.Saver and R-Studio files. They are very similar to each other. However, the first application is simpler and designed to be used by users with initial knowledge, and the second program is able to play even modified file systems, not to mention that it restores such objects, the existence of which users are not even aware of.
In any case, you just need to select a partition or media, activate the start of scanning, and then, when viewing the results, select the desired file and restore it, indicating the desired location.
Note: when using the first portable application, you cannot specify the section in which the program file (R.Saver.exe) is saved for scanning!
And one more reservation regarding some situations concerning the fact that Kaspersky deleted the files. How to recover information in the second program, if you did not find the desired object in the main results?
To do this, you will need to use a special additional directory. It usually contains multimedia files, however, it is also impossible to exclude the option of the presence of the object you need there, so it is better to spend time and analyze the results in all the folders presented. It is possible that in them you will find even those files that were considered irretrievably lost.
