Trojan.LockScreen - updated Jan 2021

What is Trojan.LockScreen?

Trojan.LockScreen – ransomware that locks all data on the system with AES encryption algorithm

Trojan.LockScreen is an especially dangerous cyber threat that belongs to the trojan and ransomware categories. Its main goal is to encrypt all personal files on the device with the help of AES cipher and then demand ransom for a decryption tool. The attackers typically ask for 0.2 bitcoin for it, although this sum might vary from person to person.

Unfortunately, cybercriminals are right about one thing: only they have decryption software that could decrypt your data. Cybersecurity researchers actively advise users to avoid contacting malicious actors, as they might not fulfill their promises, resulting in monetary losses.

Mostly, Trojan.LockScreen infection comes inside its target PC system undetected. Once inside and active, this trojan horse starts playing one of the most important roles in the functionality of the Ukash and Police virus. In addition, it is known that it has also been involved in the propagation of:

• Cryptolocker,
• CTB Locker,
• Cryptowall, and similar ransomware.

Please, stay away from these threats as far as you can because they are capable of blocking important files and then asking to pay a ransom in exchange for unblocking them.

Typically, such viruses are interested in the most commonly-used files (and Trojan.LockScreen is no exception) such as:

.jpg, .gif, .mp4, .pdf, .doc, .html, .zip, .rar, .psd, .dat, .txt, etc.

Unfortunately, it is very hard to unlock encrypted files without a key, held by cybercriminals on a remote server. If you are in such a situation right now, you should waste no time and disconnect your PC from the Internet and perform a full Trojan.LockScreen removal.

Also, make sure you scan your computer with updated anti-spyware to remove infected files from it. Finally, you should try the available decryption tools provided by various security teams. Additionally, we provide alternative methods for data recovery below.

Ransomware is commonly spread via spam email attachments and hyperlinks

While there is still unknown the exact scheme of Trojan.LockScreen propagation, security experts guess that this trojan infection relies on spam and infected email attachments. That's why you should stay away from suspicious emails that were sent to you by a person that you don't know.

Also, make sure that you monitor the installation of free software because you can never know how harmless or harmful it may be. If Trojan.LockScreen infects a computer; it scans it and starts looking for predetermined files. After finding them, a virus encrypts them and starts showing the huge alert message belonging to the Ukash virus or one of crypto-ransomware.

Note that this trojan can also be used for various other purposes and can perform the following actions (to revert these changes, we highly recommend FortectIntego):

• modify Windows Registry
• remove or download certain files
• steal information, etc.

As we have already mentioned, Trojan.LockScreen gets inside the system with a help of various means of distribution, like freeware, shareware and similar. Once it gets inside, it downloads ransomware on the PC and causes other unwanted changes.

Typically, with the help of Trojan.LockScreen, you can get infected with FBI Moneypak, FBI Green Dot Moneypak virus, IPA virus, and similar malware. They all act almost identically: they display a huge alert that looks like it was sent by governmental authorities and says to the user that he has been doing illegal activities on his computer.

That includes spreading copyrighted content, watching pornographic videos, or even spreading malware. Additionally, they require to pay the fine for all these activities.

Manual Trojan.LockScreen removal is out of the question

As you can see, Trojan.LockScreen removal should be performed as soon as possible, as it might continue encrypting the incoming files or start collecting personal information such as passwords and logins. However, this process should only be performed after making copies of all the affected files on your computer; otherwise, in case something goes wrong, they might be damaged permanently.

After you back up the encrypted data, you should remove Trojan.LockScreen ransomware from your machine. To do that, you should download and install a reputable anti-malware program, such as SpyHunter 5Combo Cleaner, and perform a full system scan. After that, you should also take care of Windows system health with the help of the FortectIntego repair tool.
