Did McAfee antivirus remove important files or sent them to the quarantine after scanning the computer for viruses? If you’re interested in the best methods to restore files from the quarantine or recover deleted data, here’s the article you need.
Introduction
All kinds of malware or viruses are created and used to sneak into a user’s computer and steal, destroy or damage user data, or use such data for malicious activities.
The list of malware threats is huge, and it is only growing longer and longer every day. That is why leading computer security experts are busy developing specialized software intended to protect all kinds of data and prevent unauthorized access to users’ computers, and ensure security of personal and confidential information.
However, when there is a threat of a virus attack or damage to user data, the protective mechanisms of such antivirus software may perform a forced deletion of infected or suspicious objects to the program’s safe storage, for curing or finally removing them, if the threat cannot be eliminated otherwise.
As a result, users often lose important files, confidential correspondence (personal or business), family photos and video archives, and other data. However, all that information is not lost yet, and it can be restored either from the antivirus quarantine, or with the help of a specialized data recovery tool. In this article, we will find out where the antivirus keeps quarantined files, how to extract the files you need, and how to restore the deleted data if you can’t find them in the quarantine.
Recover files from the «McAfee» quarantine
The people behind various malware always keep track of modern antivirus developments and update their viruses to search for new vulnerabilities and trap doors that enable unauthorized access to user data. Often, they disguise virus activities so these look like white-list apps, or even implant viruses into ordinary files.
«McAfee» security solutions include software tools for diagnostics, detection and blocking of possible virus threats. When performing its protective functions, the antivirus compares activities of applications and execution of specific files with a database of already known threats) and it may delete or move to a safe storage (quarantine) an infected file or a file that looks like a potential threat, so that any further use of such file is blocked permanently. The main argument for isolating a file into the quarantine is the heuristic check. This kind of check lets the program search for potential threats by evaluating behavior patterns. As long as there are certain signs (for example, self-replication, or the ability to overwrite system data with its own code), the antivirus makes a justified decision to isolate such an object.
Sometimes the elements recognized to be dangerous may be sent to the quarantine by mistake. In this case, they should be restored if the user needs them for certain purposes.
Open a «McAfee» antivirus on your computer, using any method you prefer. For example, right-click on the antivirus icon you can see on the «Taskbar», in the lower right corner of the screen near the notification area, and select «Open McAfee Total Protection» from the context menu.
In this article, we are going to describe the procedure for «McAfee Total Protection», but this algorithm for restoring files from the quarantine will work similarly with all products of this company.
In the main window, click on the «Navigation» button shaped as a gearwheel, and open the nested menu. From the list of possible actions, select «Quarantined items» in the section «Settings».
In the new window «Anti-Virus and Anti-Spyware», open the element «Quarantined items» to search for blocked files.
You will see a table; select the files you need by clicking on every file, or click «Select All», and then click «Restore». This action will cancel the quarantine status of the selected items and will restore them to their original locations.
Note: Don’t restore items from the safe storage you are not sure they are absolutely harmless – doing it, you are taking a risk of infecting the entire operating system and losing all data on a specific computer.
If you haven’t found the necessary files in the safe storage, they can be recovered with third-party data recovery tools, and this is the final part of today’s article.
Recover deleted files from a backup
One of the important elements in any user’s strategy for data security is using backups – that is, regularly creating archives of important files, at the user’s choice. In an emergency, when your files are lost, damaged or removed due to malware effects, you can always go back to a previously created backup and restore the latest version of the files you are looking for.
The family of «Windows» operating systems features the integrated backup option, which, if configured properly, can help you archive your data using standard tools, and this way, secure them against any virus-related problems.
However, it takes quite a lot of disk space to create and store several backups, and low disk space is one of the most widespread problems for present-day users who tend to create, store and use increasingly large pools of data. That is why most people who do make backups tend to archive only important system files which are vital for the work of their computers.
Also, any computer can come under attack at a moment between two planned backup sessions. Another possible scenario is that a virus may destroy or damage a backup copy which means losing important data again.
That is why it is always a good idea to have a multi-purpose professional data recovery tool which can restore the missing files for sure.
Restore lost files with third-party file recovery software
It is not always possible to recover files deleted by an antivirus using standard methods. The quarantine may be empty, or the files you are looking for might be missing, while the backup you hoped for could be damaged or lost. In this case you should use third-party solutions for recovering deleted files.
Such programs are usually based on the two methods, in-depth search and signature analysis, which help to find the beginning and the end of each file, restore its structure, and present the file for the user to view and save. Most utilities of the kind have only moderate rates of successful file recovery, or offer a limited set of options which make it impossible to restore the necessary data entirely.
However, there a few globally recognized names in the data recovery market, and results of independent tests run by specialized labs as well as large-scale feedback from end users suggest that the leading position belongs to «Hetman Software» and its flagship product, Hetman Partition Recovery.
This tool combines the company’s best know-hows in the field of searching, identifying and recovering data which was deleted, lost, damaged or unavailable for a number of reasons. Thanks to its integrated innovative algorithms, any information can be recovered quickly and almost to the fullest extent. In most cases, this tool is really indispensable when you need to recover files after:
Deletion – regardless of what method of deletion was used (simple or permanent), or what specialized cleaning tool was applied, and after deletion by mistake from all kinds of devices.
Formatting – it can bring your data back after formatting a partition or an entire hard disk with standard tools integrated into a «Windows» operating system or with specialized utilities, after changes to the file system, or when file allocation tables are damaged or missing.
System failure – recover data after an operating system crash, hardware failures, and software errors including firmware issues.
Hard disk defects – restore information after physical defects of storage devices, when they become unreadable, corrupt or inaccessible.
A special feature of «Hetman Partition Recovery» is its ability to recover successfully any files that were lost, deleted, damaged or inaccessible because of virus effects. All kinds of malicious scenarios, for example, destruction of all data, removal by an antivirus program because of virus infestation or potential threat, blocked or limited access, modified or damaged files – all these things can’t prevent the program from finding and recovering user data from all kinds of storage devices.
Download the latest version of the program’s installer from the official website of «Hetman Software» and run it. The step-by-step wizard will help you decide on the program’s optimal settings and get it ready for use. When the installation process is over, open «Hetman Partition Recovery». The program will run an initial system scan, search for all connected devices and get them ready for a full-fledged scan by displaying them in the main window.
