The malware can spread Microsoft support scams by showing the "Trojan_Spyware Alert - Error Code #0x268d3 (!x3)" fake alert
In some cases, when Windows computers got infected with VirTool:Win32/DefenderTamperingRestore, their screens were locked, and pop-ups stating that “Trojan_Spyware Alert – Error Code #0x268d3 (!x3)” was detected.

Trojan_Spyware Alert – Error Code #0x268d3 (!x3)
Access to this PC has been blocked for security reasons.
Contact Windows Support: +1-888-210-6024
Please do not do that. You might be tricked into revealing your personal details and purchasing rogue system tools that are worthless by calling the provided number. Cybercriminals might also ask to grant them remote access to the infected PC to “resolve” the issues.
If you allow them remote access, they could upload additional malware onto your device, steal your files, or do whatever else they please. Unlock the screen by pressing Alt + Ctrl + Del and opening the Task Manager. Identify the running process and end its task. If that doesn't help, reboot your device in Safe Mode with Networking and perform a full system scan with one of our recommended security tools.
Download the time-proven Malwarebytes security software and, after updating it – scan the entire system. It should detect and remove VirTool:Win32/DefenderTamperingRestore virus.

Most popular malware distribution techniques
There are tons of different infections lurking on the internet. Your best chance to avoid them is to acquire a reliable anti-malware tool with real-time protection. Cybercriminals are creating new malware daily, and the spreading techniques are getting more and more elaborate.
One of the most prevalent malware distribution methods is still via infected email attachments and deceptive hyperlinks. The main attribute of a spam/phishing email is the sense of urgency that it creates by pushing you into downloading its attachment or clicking on a link. Please be aware of them and don't download anything if you don't know the sender, the email has grammatical mistakes, or raises any other flags.
Another sure way to catch some sort of an infection is by using file-sharing platforms, especially popular torrent websites. Cybercriminals upload their vile creations camouflaged as software cracks and wait for unaware users to download them. As soon as a payload file is executed, the infection spreads immediately. Refrain from using such platforms if you value your privacy and security.

How to prevent from getting malware
A proper web browser and VPN tool can guarantee better safety
As online spying becomes an increasing problem, people are becoming more interested in how to protect their privacy. One way to increase your online security is to choose the most secure and private web browser. But if you want complete anonymity and security when surfing the web, you need Private Internet Access VPN service. This tool successfully reroutes traffic across different servers, so your IP address and location remain protected. It is also important that this tool is based on a strict no-log policy, so no data is collected and cannot be leaked or made available to first or third parties. If you want to feel safe on the internet, a combination of a secure web browser and a Private Internet Access VPN will help you.
Recover files damaged by a dangerous malware attack
Despite the fact that there are various circumstances that can cause data to be lost on a system, including accidental deletion, the most common reason people lose photos, documents, videos, and other important data is the infection of malware.
Some malicious programs can delete files and prevent the software from running smoothly. However, there is a greater threat from the dangerous viruses that can encrypt documents, system files, and images. Ransomware-type viruses focus on encrypting data and restricting users’ access to files, so you can permanently lose personal data when you download such a virus to your computer.
The ability to unlock encrypted files is very limited, but some programs have a data recovery feature. In some cases, the Data Recovery Pro program can help recover at least some of the data that has been locked by a virus or other cyber infection.
