Since it corrupts essential system settings, it leaves the infected system extremely vulnerable to additional malware attacks. So, instead of following the requests listed in the HELP_DECRYPT_YOUR_FILES.TXT ransom message, try removing malicious instances and restoring .scl files before another malicious app gets its chance to enter your machine.

How Does Scl Ransomware Spread?
Cybercriminals often use phishing strategies as well as social engineering tricks in order to trick people into running malicious code on their computers. Ransomware threats like Scl are well-known for accessing computer operating systems via malicious files attached to legitimate-like email messages. Links that open pages with damaging scripts may also be included in the emails messages.
Since the Internet is full of malicious software created to disrupt PC security, we all need to be very careful when browsing the web. Especially, when we visit unknown sites; click on random ads; and interact with the content of various email messages. Following all basic security measures prevents the risk of falling victim to cybercriminals.
What Does Scl Ransomware Do?
Once delivered to a target machine, the payload of Scl ransomware initiates a complex attack. Lots of malicious processes with be executed to support the attack.
At first, the threat may run an information-gathering operation. The virus will try to identify technical details about the operating system as well as the current user profile. It can also gather sensitive personal data that will be eventually used by hackers for identity theft, financial abuses and additional profit.
The virus will definitely try to make its detection harder. So, it may hijack legitimate system processes and services in order to bypass the detection of any active security measures. It may hook up to running apps and services in order to hijack the user profile, obtain administrative rights and manipulate system functionalities too.
And if hackers decide, they can run a basic Trojan module to obtain data records, deliver additional malicious files and record more details about you and your usage og the PC.
Hackers will try everything to make you more prone to pay a ransom fee for your locked .scl files. That’s why the Scl virus drops two ransom messages in an attempt to extort a ransom fee for the decryption tool. The two files named HELP_DECRYPT_YOUR_FILES.HTML and HELP_DECRYPT_YOUR_FILES.TXT show the following message:
