VirTool:Win32/DefenderTamperingRestore is a type of malware which is programmed to stop your security software from working correctly

VirTool:Win32/DefenderTamperingRestoreVirTool:Win32/DefenderTamperingRestore is a detection name for malware that attempts to disable Windows Defender defenses

VirTool:Win32/DefenderTamperingRestore is a detection name of a potential threat that is flagged by Windows Defender security software. The main purpose of the infection is to tamper with security software, weaken computer defenses, and compromise the device. Once the security software has been tampered with, it might not be able to protect users from viruses, trojans, worms, ransomware, and other types of malware.

While the initial goal of VirTool:Win32/DefenderTamperingRestore virus is to compromise security software to bypass its defenses, cybercriminals behind it may have various goals. For example, they might place a backdoor on the system in order to compromise it even further, consequently achieving the nefarious goals. Victims of such an attack might suffer from financial losses, additional malware infections, identity theft, and other privacy/security issues.

Name  VirTool:Win32/DefenderTamperingRestore
Type Malware 
Purpose To disable Tamper Protection feature of Windows Defender and bypass its security
Distribution Malware developers typically employ various distribution methods, although the most prevalent one remains spam email links and attachments
Symptoms  VirTool:Win32/DefenderTamperingRestore popup message shows up on the screen; otherwise, malware is programmed to operate without traces (some users may experience crashes, errors, and similar unexpected computer events) 
Risks Malware can affect the infected users in various ways – it can steal passwords, banking details, take screenshots, install other malware, encrypt files, and much more 
Removal Windows Defender should be able to detect and eliminate the infection; in some cases, this process might fail due to malware's functionality. In such a case, we suggest you download a reputable third-party security tool (we recommend SpyHunter 5Combo Cleaner or Malwarebytes) and perform a full system scan. If malware is tampering with other security solutions, you should access Safe Mode and perform a full system scan from there
System fix A malware infection can seriously damage Windows operating system files and settings, and security software might fail to fix these compromised items. If that happens, you should employ ReimageIntego repair software to fix virus damage on your computer

VirTool:Win32/DefenderTamperingRestore is a rather generic detection that can be encountered at any time. In most genuine cases, however, this occurrence happens when users come in contact with potentially malicious content online. In other words, cybercriminals attempt to spread the infection to as many people as possible, so they often choose multiple attack vectors for higher success chances. Here are a few of them:

  • malicious spam email attachments and embedded hyperlinks;
  • software vulnerabilities and exploit kits;[1]
  • false claims on phishing websites and fake Flash Player updates;
  • software cracks and pirated program installers, etc.

Thus, there are several ways how you could come in contact with the VirTool:Win32/DefenderTamperingRestore virus in the first place. Once the contact is made, Windows Defender might or might not detect the intrusion, as the malicious program is designed to disable certain security software defenses (mainly, Tamper Protection feature).

In case the security app does not get compromised completely, it will stop and remove VirTool:Win32/DefenderTamperingRestore successfully. However, there is also a chance that weakened defenses would prevent a successful elimination. Unfortunately, if case malware manages to break in, it can continue to operate in the background, all while anti-malware is rendered useless.

Users affected by VirTool:Win32/DefenderTamperingRestore infection can suffer all kinds of damages, as the initial infection can be used only as a pathway for other malware to be infected. For example, ransomware such as Ogdo, Geno, or MAKB can be deployed in order to lock all personal files on the device and then demand ransom in Bitcoin for their return. Other invisible infections, such as trojans, may be used to steal all your passwords, bank account details, and other sensitive information, which can be later used for malicious purposes.

Without a doubt, VirTool:Win32/DefenderTamperingRestore removal should be your top priority. This is why it is important to use additional protection when trying to defend yourself from all types of malware. We suggest you scan the machine with alternative security software, such as SpyHunter 5Combo Cleaner and Malwarebytes, to ensure that the infection is completely eliminated. Experts also advise running a PC repair tool ReimageIntego after the malware removal process.

Security software conflict issues: VirTool:Win32/DefenderTamperingRestore pop-up might show up as soon as you install third-party security tool

Some users reported that they keep getting the VirTool:Win32/DefenderTamperingRestore detection on several occasions, i.e., the infection does not go away after removing it with Microsoft Safety Scanner; according to reports, alternative security solutions, such as Norton or Trend Micro, fail to find this threat completely.[2]

In such cases, the issues seem to lie within how different security solutions interact with each other. Windows Defender uses the Tamper Protection feature that can be enabled and disabled via the anti-virus interface or Registry Editor (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Features). Some malware might attempt to tamper with this setting. However, each time a third-party security solution is installed, the Tamper Protection feature is also disabled in order to prevent false positives and allow the normal operation of the software.

Microsoft launched the Tamper Protection feature with the release of Windows 10 version 1903 in early 2019.[3] According to Microsoft, it provides additional protection from outside intervention. Unfortunately, this can also cause major conflicts when third-party security software is used, as the function is disabled each time a new anti-malware is installed.

Therefore, to stop VirTool:Win32/DefenderTamperingRestore popups, if you are using a third-party security tool and disable Tamper Protection, you should follow these steps:

  • Type in Windows Security in Windows search and hit Enter
  • Pick Virus & threat protection
  • Under Virus & threat protection settings, click Manage settings
  • Scroll down, locate Tamper Protection
  • Turn the switch to the left to turn Tamper Protection off.

VirTool:Win32/DefenderTamperingRestore removal instructions

As mentioned above, if your security software managed to catch the infection despite being tampered with, the VirTool:Win32/DefenderTamperingRestore removal process should occur automatically. In case your security application fails due to malware's main function, we advise you to download and install alternative anti-malware solutions, such as SpyHunter 5Combo Cleaner or Malwarebytes, and then perform a full system scan. If the need arises, you can also access Safe Mode with networking, as explained below, and perform a scan from there.

However, if you are unable to remove VirTool:Win32/DefenderTamperingRestore automatically and you are using a third-party anti-malware tool along with Microsoft Defender, you should disable the Tamper Protection feature to prevent software conflict from happening in the future.

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
