Virus-Infected Files

Read how to recover files deleted as of a result of a virus attack using built-in Windows or third-party solutions. How to recover virus-encrypted files.

Has your computer been subjected to a virus attack? Do you want to recover files deleted as a result of malicious activity? We will try to describe the standard ways of correcting an unforeseen situation and various ways of recovering deleted files in this article.


With the development of electronic technologies and means of communication, the range and volume of information used by users in carrying out a variety of activities directly related to their professional and production activities, as well as aimed at ensuring communication, communication, games and entertainment of the latter.

Computer devices in various designs help to fully control incoming and outgoing data flows, process them instantly, regardless of their final volume, and ensure safe storage.

Stationary personal computers and laptops, including any of their variable combinations (ultrabooks, netbooks, laptops, transformers, nettops), tablets, smartphones and communicators, etc. fully meet the ever-increasing needs of users when working with information, and meet the latest information standards.

Most widely, in the list of the most popular electronic devices among users, personal computers and laptops are presented. Rich internal filling of computer devices (superfast processors, highly functional motherboards, progressive memory strips, capacitive storage devices, etc.), and modern high-performance software, by right, allows them to occupy a leading position in processing and storage of information in the world.

Smartphones and communicators are approaching them in terms of the breadth and number of devices used. Due to their high mobility, miniaturized size, high functionality, and wide range of available applications, smartphones strive to match and, if possible, replace computers and notebooks when performing certain actions.

The development of the international computer information network “Internet” has accelerated the spread and use of a variety of computer devices by users to solve any problem without the need for binding to a particular device or workplace. The use of an extensive database, remote use and processing of information significantly popularized computer devices, and accelerated the process of transition to digital storage of information.

With the widespread adoption of digital information formats, most types of user data (personal, social, public and business) are stored, processed, transferred and maintained by a variety of computer devices. Therefore, the most important requirement for all devices is the mandatory high level of data security and protection against unauthorized actions by third parties.

One of the most common types of malicious impact on user data is malicious software virus attacks.

The range of action and functionality of such programs is extremely wide, and thanks to the international information network “Internet”, the level of their distribution has reached a global scale.

Infecting a user’s computer device with a virus can lead to undesirable consequences, the most common of which is the removal of user files. How to recover files after exposure to viruses will be discussed later in this article.

Harmful effects of viruses

The majority of computer users have heard, and many have directly experienced, the consequences of the negative impact of computer viruses, their impact on user files and the overall performance of the personal computer as a whole.

Deliberately deleting or damaging user files, blocking access to individual operating system or computer elements, selectively encrypting files and changing their structure, erasing or deleting partition tables,

Transferring control of the personal computer to criminals, using the user’s computer for remote hacking or other malicious activities, stealing personal data, sending spam messages, etc. – Only a fraction of all activities that may be caused by a virus infecting a computer device.

Modern antivirus programs have learned how to recognize and fight, isolate and destroy malicious viruses and protect computer devices from infection. However, computer viruses develop rapidly, and implement various malicious access algorithms and methods of remote impact.

Their efforts often result in the partial or complete deletion of user files, which is particularly critical when such files are stored in a single copy and do not have backups.

Backing up user files is a good element of protecting data from unexpected and irreversible loss due to viruses. Regular backups of important files will help users to protect themselves from many types of losses, both due to viruses and other causes, such as storage device failure.

However, the amount of data that users use and, most importantly, want to save is constantly growing. And it requires multiple storage devices, which entails significant additional costs.

Therefore, many users prefer to keep their backups on the same device. As a result, infecting the device with a virus can result in damage to or complete loss of not only the original files, but also the saved copies.

Therefore, the issue of recovering lost data after a virus attack is of paramount importance to users, especially in response to the loss of data.

Treatment for viruses/trojans

the main one. Configuring the system with SmartFix.

For the basic setup, we need to download the SmartFix+ file, it integrates seamlessly into the recovery environment and restarts the computer to start the treatment process.

It will take about 5 minutes, in any case you should wait for the end of the setup. When the desktop reappears, a progress report will open in the taskbar, and if you don’t understand much about it, just close it.

In most cases, that’s all, the computer is cured and there is no need to do anything else, but you can do the following steps to check it out.

A control check. Autoruns checks the autoload with Autoruns.

It will take some experience to recognize malicious autoruns manually. Click Start -> SmartFix -> Troubleshooting, then select Autoruns and click Start.

The Autorun check box opens, you need to wait until “Ready” appears in the lower left corner of the program and the “Hash submitted” entries are left in the VirusTotal column. Now you need to pay attention to the lines opposite which there are red numbers in the VirusTotal column, they indicate the number of positive responses to the total number of antiviruses.

Be careful, not all entries here are malicious, there are many false positives. If you are sure that a record is malicious, you can disable it by checking the box on the left side of the line.
