The email that criminals would like to receive your questions remains the same. So the ransom note pops-up as a lock screen and encourages victims to receive further payment instructions via email.

IT files virus even includes the IT movie poster for the scariness of the initial ransomware attack. However, when you try to unlock the screen and put the key, anything, in general, you get mocked with a “wrong. hahaha” reaction. Cybercriminals are not emphatic and they only care for the profit, not your files or belongings.

Make sure to remove IT ransomware and do not think about paying these people. There is no need to believe or trust them, so keep your money and get the proper anti-malware tool instead. There are no other options since the decryption tool is not developed yet. Thrid-party options can help, but the most reliable technique is anti-malware tools and your file backups stored on the external devices.

Ransom-demanding threats spread using stealthy methods and rely on malicious files

The infection might get spread using a payload dropper that initiates malicious script injection after the malicious macro virus triggering or when the particular trojan, worm, other pieces of malware installs the cryptovirus on the machine. File-sharing, torrent, operating sites, and platforms can be one of the many methods that distribute malicious files to systems via the internet.

Even websites that get malicious scripts loaded as additional layers can trigger such drops of the file that includes pieces of cryptovirus. Unfortunately, spam emails sent from unknown companies or people also pose the risk to your data and the machine. If you visit the link provided in the message or download the file attached, you can trigger the infection unknowingly.

Once the script is launched, the encryption process can start and you will only notice the infection after data gets locked and a ransom demanded. Pay attention to all the details, red flags and avoid content that is suspicious or seems harmful, especially unfamiliar files, if you want to avoid these serious infections.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
