What Cloud Packager virus does on an infected PC
From our report of Oct 2017 · not reviewed since
Cloud Packager miner hides under the names of Windows processes
Cloud Packager is a Trojan horse that is designed to mine digital currency (Bitcoin, Monero, Dashcoint, etc.) by using affected computer's CPU and GPU processing power.
Generally, mining is not illegal activity. However, this malicious program uses computer's resources without asking user's permission; and it's definitely illegal.
Cloud Packager miner is mostly spread via cracks, adware bundles, and other potentially unwanted programs. In this way, the trojan can sneak inside the system unnoticed. However, the sings of the malware attack are clear - extremely slow computer's performance.
Once Cloud Packager virus enters the system, it creates two miners that have different purposes. One of them - NvProfileUpdater64.exe - is designed to use computer's GPU or video card. The second one - wdf.exe - uses computer's CPU processing power. Both of these processes are visible in the Task Manager.
However, the NvProfileUpdater64.exe miner uses the name of NVIDIA driver profile updater in order to trick users that it's a legit process. The wdf.exe uses the name of the Microsoft to hide its malicious tasks. But keep in mind that legit processes cannot use 70% or more of the computer's resources.Thus, seeing such entries is the main sign that your computer is used for mining cryptocurrency.
Other signs that your computer might be infected with Cloud Packager virus are:
If you recognized at least one of these symptoms, you should scan the system with or another malware removal tool to remove Cloud Packager miner from the device. The high usage of the computer's resources might result in overheat. When your PC works in the high temperature for a long time, it might burn out.
Thus, this cyber threat might cause physical damage to your device. It goes without saying that you should not delay Cloud Packager removal in order to avoid losing your computer as well as all the important data saved in it.

How Cloud Packager virus got on your PC
From our report of Oct 2017 · not reviewed since
The Cloud Packager hijack might occur if you download freeware or shareware incorrectly.
It means that when you download some free program from the Internet, you have to monitor the installation process and make sure that you do not agree to download any "optional downloads." For this reason, you should follow safety tips created by Los Virus security team:
- always choose reliable download sources;
- read EULA, Privacy Policy or other provided documents before installing an application. If these entries are not provided, do not install the app;
- choose Advanced/Custom installation instead of Quick/Recommended;
- read notifications in each of the steps and unmark pre-selected additional downloads (if there are any).
How to check the PC for Cloud Packager virus
- File:
NvProfileUpdater64.exe
How to remove Cloud Packager 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 NvProfileUpdater64.exe runs from and stop it
NvProfileUpdater64.exeis 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.

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 Cloud Packager 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 Cloud Packager 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.

Removal of the Cloud Packager Trojan
If you suspect that mining trojan may have been installed on your device, you should obtain a reputable anti-malware software and run a full system scan.
Tools like or can quickly remove Cloud Packager as well as other PUPs or cyber threats that may have been installed on your device as well.
However, if for some reason you cannot run automatic Cloud Packager removal, you should reboot the computer to the Safe Mode with Networking. Sometimes malicious programs can block access to security software to stay longer on the device.
[GI=method-1]If you cannot run automatic Cloud Packager removal, follow these steps:
[GI=method-2]This method might also help to disable the virus in order to remove it:
After removal: passwords, accounts and prevention
Accounts come next
Because the PC showed an unfamiliar process called NvProfileUpdater64.exe in Task Manager, a sign of a program that could read browser data, the clean-up is only half of the work.
The other half happens in your online accounts.
Change passwords from a clean device, beginning with e-mail; sign out of all sessions; check forwarding rules and recovery phone numbers; and turn on two-step verification with an authenticator app or a passkey. Ask your bank to replace cards saved in the browser.
Why the order matters and what to check in each account: secure 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 Cloud Packager virus
What is NvProfileUpdater64.exe 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 NvProfileUpdater64.exe 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.
Can I end NvProfileUpdater64.exe in Task Manager?
Ending an unknown process is safe in the sense that Windows will warn you before you close anything critical, and a restart brings back whatever Windows needs. Ending NvProfileUpdater64.exe will not remove it, though: if a task or startup entry launches it, it returns at the next sign-in.
Use ending the process as a test. If something important stops working, it belonged to a program you use. If nothing changes and it comes back by itself, find and disable its starter, delete the file and scan the PC.
Can I just delete NvProfileUpdater64.exe?
Deleting NvProfileUpdater64.exe by hand rarely removes Cloud Packager 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 Cloud Packager virus, they are a strong reason to follow the full plan.
Can I keep using the PC while Cloud Packager virus is on it?
Not for anything that matters. As long as the program behind an unfamiliar process called NvProfileUpdater64.exe 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.
Should I reset my PC because of Cloud Packager virus?
Only if the signs point to deeper access. Reset when you see an unfamiliar process called NvProfileUpdater64.exe 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 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 Cloud Packager 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.
Is Cloud Packager virus a known trojan?
Not as a documented family, at least not yet. What is known is the visible sign, an unfamiliar process called NvProfileUpdater64.exe 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 Cloud Packager 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.
Will Fortect remove Cloud Packager 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 Cloud Packager 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.
