What Lucifer virus does on an infected PC
From our report of May 2020 · not reviewed since
Lucifer virus is the trojan that infects the machine and resides in the memory, so malware cannot be easily detected
Lucifer virus – malware that is classified as a banking trojan because it focuses on getting the online banking-related information from the victim.
This threat aims to steal valuable information related to email, e-commerce, and streaming platform accounts and banking credentials, so additional malicious operations can be performed using logins and passwords. It spreads worldwide, even though most of the attacks were reported on Larin America, North America, Europe, and Asia.
This threat complicates the detection and can be concealed in the background for a long time because it resides in memory and splits malicious code into several files placed across the system.
This is the sophisticated malware that targets banking data by monitoring websites that user visits. When Lucifer malware finds possible target websites in browsing history of the victim it can activate keylogging tools and take screenshots or directly gather information by recording various inputs that user fills on banking sites and other platforms.
Cybercriminals try to obtain login credentials and other information that can be valuable and used in later attacks or enables them to make transactions of payments. These universal keylogging, and data tracking, or exfiltrating functions can help the malware expand and make the virus more dangerous when other types of details get stolen or even compromised.
Lucifer virus endangers the security of affected device users because attackers can access accounts and infect the machine directly with additional malware.
Such trojans can be set to run on resources in the background but also act as a backdoor malware that allows intruders or remote attackers to access the system and control all the functions. If you have passwords automatically stored on the web browser those details can easily get exfiltrated by this malicious worm.
The silent Lucifer malware can employ the infected system to distribute email spam to other devices and stolen passwords and login information is extremely valuable for such purposes. When emails get hijacked accounts connected to them can be also stolen using additional tools and accounts may be requested to reveal other details or lend money for the said friend or contact.
Lucifer virus can get money, data, and scam other people while under the disguise of a genuine person whose email account gets hacked. Fraudulent transactions can be made from financial accounts when trojan steals logins and passwords to those platforms.
There are many ways that malware can use all the stolen details, so the infection may be terminated, but you need to still think about results and damage left on the machine besides be cautions later on.
Lucifer banking trojan itself is mainly spread using email campaigns when malicious files get dropped by attaching malware to common types of files and documents. This method can be used later on by the same attackers, so additional malware is delivered to your contacts or friends. Be cautious of the possibility that malware will hit your device again and actors may try to scam you.
Lucifer virus can be used to hide files and processes associated with the same malware or even other programs. When the victim looks for some items on the computer, data cannot be found and removed.
It infects the machine and remains undetected for as long as it wants because it manages to reside in the memory and is less than 1,136 bytes per program. Lucifer virus arrives on the machine with the help of an email attachment included on the notification with subject line Lucifer will soon rise to the power that should of been his!.
This email contains the short message "thou shall give you thy soul to LUCIFER..." and once opened the attachment GRAND.BEAST.VBS triggers the drop of malicious scripts all over the system and startup files, other data that changes settings of the system and attempts to send malicious files in other parts of the machine add entries in contacts, email accounts.
Lucifer virus adds shortcuts and redirects to malicious sites, created hidden directories, and injects scripts into various channels, so copies of the malware get triggered more often. This threat can be detected by various names like VenoM.Lucifer.A, but these names shouldn't be an indication of the threat.
When you use anti-malware tools and check the machine for intruders, there might be tons of different detection. Pay attention to results, not names, and clear those files off of the PC regardless of the particular detection name.
You need to remove Lucifer virus, so the program needs to find it and other associated or potentially related programs and files - a full system scan with the anti-malware tool can ensure this. Some of the particular variants can use rootkits and remain unnoticed on the computers the malware has infected.
If you have difficulty to detect and remove the Lucifer virus, you may need to reboot the machine in Safe Mode with Networking and launch your anti-malware tool then. This feature gives the opportunity to disable some programs, including the disabling of security tools, so malware can be detected.
Also, remember about additional steps besides the Lucifer virus removal because it has additional characteristics and uses automatically installations of worms to control the behavior and infection. You may need to fix some damage before you can use the machine normally again, so run to repair system files and functions automatically.

How Lucifer virus got on your PC
From our report of May 2020 · not reviewed since
Worms spread around as trojans, ransomware, and other more severe malware does - using spam email campaigns and malicious file attachments as vectors.
Irrelevant emails and suspicious messages that you were not expecting to get should raise questions and indicate possibly dangerous content. If you get anything questionable - pay close attention or delete notifications without considering to open them.
As we mentioned, threats like this can steal logins, emails, and passwords to misuse them in later attacks, so you may receive targeted emails with malicious attachments and infect the machine by clicking a few links or buttons on the suspicious email. In most cases, the bigger the malware the more stealthy it is.
To ensure that the system is free of malware and cannot get affected by threats like this, you should keep the AV tool running on the machine. Some security applications provide the option to check files before you download or open them, so you can avoid the infiltration in advance and keep the machine virus-free entirely.
How to check the PC for Lucifer virus
- File:
BEAST.VBS
How to remove Lucifer virus
A loader's job is to install other malware, so treat the PC as infected with more than one program until the scans are clean.
Step 1: Check where BEAST.VBS runs from and stop it
BEAST.VBSis the part you can see, and its location tells you whether it belongs there. Right-click it on the Processes page of Task Manager and choose Open file location, then right-click the file > Properties > Digital Signatures to see who signed it.An unsigned file, or one in a user folder such as
%AppData%, is the one to remove: end the task, then delete the file.Note the folder name, because the same folder usually holds its other files. This is the same in Windows 11 and Windows 10.
Full procedure with screenshots: Close a frozen app (Task Manager, Force Quit) On uGetFix
Step 2: Delete scheduled tasks that bring it back
Open Task Scheduler from the Start menu and click Task Scheduler Library. Select each task you do not recognise and read the Actions tab:
- a task that starts a file in
%AppData%or%Temp% - runs
powershellwith a long encoded line - opens a web address belongs to Lucifer virus or a similar program
Right-click such a task and choose Delete, and check the subfolders too. Leave tasks from Microsoft, your PC's maker and programs you use. Task Scheduler is the same in Windows 11 and Windows 10.

Windows 11: Task Scheduler Library, the task selected, the Actions tab shows the file it runs. Full procedure with screenshots: Remove what malware leaves behind in Windows
- a task that starts a file in
Step 3: Remove it from startup
Whatever Lucifer virus installed usually starts with Windows. Open Task Manager with Ctrl + Shift + Esc, go to Startup apps in Windows 11 or the Startup tab in Windows 10, and disable what you do not know, starting with entries that have an empty Publisher column.
Open file location on the right-click menu shows the file, which helps you decide and tells you what to delete later. Disabling is safe: if something you need stops working, switch it back on.

Step 4: Delete the folders left behind
What the uninstaller leaves behind is usually in the user folders. Open File Explorer, switch on View > Show > Hidden items (in Windows 10 View > Hidden items), and go through
%LocalAppData%,%AppData%, %ProgramData% and the two Program Files folders.Sort by Date modified and delete folders that appeared together with the problem and belong to no program you use. Folders with random names that hold
.exe,.dll, .js or .ps1 files are the strongest sign.Full procedure with screenshots: Remove what malware leaves behind in Windows
Step 5: Scan the PC, then run the offline scan
Open Windows Security > Virus & threat protection > Scan options, run a Full scan and remove everything it finds. Then select Microsoft Defender Antivirus (offline scan) and click Scan now: the PC restarts and scans before Windows loads, which finds files that hide while Windows runs.
Save your work first, because the offline scan takes about 15 minutes. Both scans are built into Windows 11 and Windows 10, and a second scanner from another vendor is a useful extra opinion.

Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan
Step 6: Change passwords from another device and sign out other sessions
Assume that the passwords saved in this PC's browsers, and the accounts that were open in them, are known to the attacker. From a phone or a clean computer, change the e-mail password first, then banking, shopping, social and gaming accounts.
Use each service's option to sign out of all other sessions, because stolen cookies keep a session open even after a password change. Turn on two-step verification on each account. Wait with the infected Windows 11 or Windows 10 PC until the scans are clean.

Manual removal using Safe Mode
Important! →
Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete. Therefore, we highly advise using the automatic method provided above instead.
Step 1. Access Safe Mode with Networking
Manual malware removal should be best performed in the Safe Mode environment.
Windows 7 / Vista / XP
- Click Start > Shutdown > Restart > OK.
- When your computer becomes active, start pressing F8 button (if that does not work, try F2, F12, Del, etc. - it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
- Select Safe Mode with Networking from the list.

Windows 10 / Windows 8
- Right-click on Start button and select Settings.

- Scroll down to pick Update & Security.

- On the left side of the window, pick Recovery.
- Now scroll down to find Advanced Startup section.
- Click Restart now.

- Select Troubleshoot.
- Go to Advanced options.

- Select Startup Settings.

- Press Restart.
- Now press 5 or click 5) Enable Safe Mode with Networking.

Step 2. Shut down suspicious processes
Windows Task Manager is a useful tool that shows all the processes running in the background. If malware is running a process, you need to shut it down:
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Click on More details.

- Scroll down to Background processes section, and look for anything suspicious.
- Right-click and select Open file location.

- Go back to the process, right-click and pick End Task.

- Delete the contents of the malicious folder.
Step 3. Check program Startup
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Go to Startup tab.
- Right-click on the suspicious program and pick Disable.

Step 4. Delete virus files
Malware-related files can be found in various places within your computer. Here are instructions that could help you find them:
- Type in Disk Cleanup in Windows search and press Enter.

- Select the drive you want to clean (C: is your main drive by default and is likely to be the one that has malicious files in).
- Scroll through the Files to delete list and select the following:
Temporary Internet Files
Downloads
Recycle Bin
Temporary files - Pick Clean up system files.

- You can also look for other malicious files hidden in the following folders (type these entries in Windows Search and press Enter):
%AppData%
%LocalAppData%
%ProgramData%
%WinDir%
After you are finished, reboot the PC in normal mode.

Removing infected programs may not be enough to terminate Lucifer virus
Lucifer malware is not a regular infection that could be found as a program on the machine and removed by uninstalling or deleting the application.
Unfortunately, malware breaks the script into many parts and adds files with the malicious script in various places of the system, so it is more difficult to get rid of the virus.
The better Lucifer virus removal option is an automatic system scan. By relying on anti-malware tools that are designed to spot and delete malicious files, you ensuring that trojan can be found and terminated alongside other payloads of malware. or security programs could be helpful for this step.
Besides the need to remove Lucifer virus, you should also think about virus damage elimination and PC repair issues. You cannot find all the altered files and registry entries or parts of the programs and system functions that worm or the trojan itself affected. Fortunately, tools like can find and fix such problems for you without causing more damage to processes and apps.
[GI=method-1]You may need to reboot the machine in Safe Mode with Networking, so the trojan can be fully terminated using AV tools
[GI=method-2]System Restore can be a useful feature for the trojan removal because it enables the function of recovering the system in a previous state
After removal: passwords, accounts and prevention
Secure your accounts after the clean-up
Assume that whatever was saved in the browsers on this PC while the PC showed an unfamiliar process called BEAST.VBS in Task Manager has been copied:
- passwords
- cookies
- autofill data
Work from a clean device, or from this PC once the offline scan finds nothing.
Start with your main e-mail account, because it can reset everything else, then banking and payment, then social and gaming accounts. Change each password, sign out of all sessions and turn on two-step verification: Turn on two-step verification / secure a hacked account.
The full order, including crypto wallets and card replacement, is in securing your accounts after malware.
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 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, can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
Questions about Lucifer virus
What is BEAST.VBS and why is it running?
Every process is started by something:
- a program you installed
- a Windows service
- a scheduled task
- a startup entry
To learn why BEAST.VBS runs, find its file with Open file location in Task Manager, then look for an entry pointing to that file in Settings > Apps > Startup and in Task Scheduler.
Sort Installed apps by date to see what arrived when the process first appeared. Once you know the owner, you can decide whether to keep it, switch it off at startup or uninstall it completely.
BEAST.VBS keeps coming back. What should I do?
A process that returns after you end it has a restart mechanism, and that is a reason to treat BEAST.VBS as unwanted. Check Settings > Apps > Startup, Task Scheduler and the Services list for entries pointing to its folder, and disable them.
Look in Installed apps for anything added the same day and uninstall it. Then delete the folder and run a Microsoft Defender Offline scan, which works before Windows starts and can remove files that are locked or hidden while the system is running.
Can I just delete BEAST.VBS?
Deleting BEAST.VBS by hand rarely removes Lucifer virus. While the trojan runs, Windows may refuse to delete the file, and if you succeed, a scheduled task, a service or a second copy may bring it back at the next restart.
The file can also be only one part of the infection: loaders and remote access tools often install other programs. Use the Microsoft Defender offline scan, which removes the file together with its startup entries before Windows loads, and then check startup items and scheduled tasks as described in the plan.
What are the signs of a trojan infection?
Most trojans try to leave no visible signs, so look for side effects. Common ones:
- Windows Security turned off or unable to update
- new entries in Startup apps or Task Scheduler
- programs in Installed apps you did not install
- browser settings that changed by themselves
- unusual network activity while the PC is idle
- password-reset or login-alert e-mails you did not trigger
None of these proves an infection on its own. Together with an antivirus alert naming Lucifer virus, they are a strong reason to follow the full plan.
Should I reset my PC because of Lucifer virus?
Only if the signs point to deeper access. Reset when you see an unfamiliar process called BEAST.VBS in Task Manager again after removal, when Windows Security cannot start or update, when remote access tools you did not install keep appearing, or when you simply cannot trust the PC any more.
Otherwise, the plan in this guide plus an offline scan is enough. If you do reset, choose Remove everything and Cloud download for a fresh copy of Windows, restore only documents and photos, and reinstall programs from their official sites. Change important passwords from the clean system afterwards.
Is Lucifer virus a known trojan?
Not as a documented family, at least not yet. What is known is the visible sign, an unfamiliar process called BEAST.VBS in Task Manager, which matches a hidden program working for someone else.
New threats are often seen by victims weeks before researchers publish anything about them. Treat Lucifer virus as you would any trojan:
- remove what starts it
- run an offline scan
- change passwords from another device
If a scan reports a detection name, keep it; it usually reveals the family and whether it is known to download other malware. We update this guide when an analysis appears.
Can a normal remote support program be a backdoor?
Yes. Tools such as AnyDesk, TeamViewer and ScreenConnect are legitimate, but whoever controls the account behind them controls the PC. Scammers install them during fake support calls, and some trojan campaigns install them silently because antivirus programs do not flag a genuine, signed product.
If you find one you did not set up, uninstall it, check Startup apps for related entries and change passwords from another device. If money or accounts were involved, call your bank and report the incident.
Can I keep using the PC while Lucifer virus is on it?
Not for anything that matters. As long as the program behind an unfamiliar process called BEAST.VBS in Task Manager runs, it can see what you type and what the browser stores, and it may download more malware. Disconnect the PC from the internet while you remove it, and do your banking, e-mail and password changes from another device.
Once the offline scan finds nothing and the sign does not return after a few restarts, normal use is fine. If the scan keeps finding new items, or you cannot remove the startup entry, a reset of Windows is the safer choice.
Is a trojan infection worth reporting to the police?
If there was harm, yes. Unauthorised payments, accounts used for fraud, blackmail or a remote session during a scam call all belong in a report, and banks often ask for its reference number before they refund anything.
If antivirus caught Lucifer virus before it ran and nothing was misused, there is nothing to report. Keep the evidence anyway:
- protection history
- the original download
- the dates
Businesses may also have to notify a data protection authority if personal data could have been accessed.
Will Fortect remove Lucifer virus?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For Lucifer virus, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
