What UNP Campaign Manager does on an infected PC
From our report of Jun 2021 · not reviewed since
Safe-looking emails might contain malware payload files
Various types of file formats are commonly used on the device and found on a daily basis.
Unfortunately, this information is helpful for malicious actors too because they develop products based on this fact and deliver their malware programs thinking about users' habits.
Maliciously infected documents, archives, PDFs, or executables get attached to emails with subject lines like:
When the sender is disguised as a well-known service or company name, these emails look safe and non-suspicious. However, when you download the attachment and open it on the system, you get the suggestion to enable the content. This is the step where you trigger a malicious script, and the payload dropper launches malware on your machine leading to cyber infiltration.

How to remove UNP Campaign Manager
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 UNP.exe runs from and stop it
UNP.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 UNP Campaign Manager 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.

Step 3: Remove it from startup
Whatever UNP Campaign Manager 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.

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.

After removal: passwords, accounts and prevention
Your passwords after UNP Campaign Manager
Removing UNP Campaign Manager does not undo what it may already have sent out while the PC showed an unfamiliar process called UNP.exe in Task Manager.
Treat saved browser passwords and logged-in sessions on this PC as known to the attacker.
From another device, change the e-mail password first and end all its sessions. Then do the same for the bank, PayPal, Microsoft, Google and Apple accounts. Stolen session cookies keep working after a password change until you sign out everywhere.
Move crypto to a new wallet created on a clean device. A step-by-step order for every kind of account is in our guide to account security after an infection.
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 UNP Campaign Manager
What is UNP Campaign Manager?
It is a trojan associated with Game Cracker software developed by Dark Bay Ltd. The malicious application launches as an executable file named UNP.exe or UNPCampaignManager.exe. Neither of these variations belongs to the Windows operating system because they represent genuine trojan horses, which are among the most dangerous cyber threats.
The trojan may hide in system folders or other common directories to convince users it is legitimate. Users often report processes appearing unexpectedly, especially after OS updates, causing confusion about their origins.
Is UNP Campaign Manager a real Windows process?
No, it is not a legitimate Windows process. Although the file format belongs to software that runs on Windows systems, UNP.exe is not an essential part of Windows. The file is specifically associated with Game Cracker, a malicious application.
The trojan disguises itself by residing in system folders and using executable file formats common in Windows. Do not trust its legitimate appearance; it is a genuine malicious threat requiring immediate removal.
What damage can UNP Campaign Manager cause?
The trojan causes multiple system errors related to processes running on your device. Users report frequent freezes, crashes, or system slowdowns when the infection is active. Common error messages include "UNP.exe is not a valid Win32 application" and "UNP.exe has encountered a problem and needs to close."
These errors indicate genuine trojan infection capable of causing further damage. The malware distributes other malicious programs or serves as a backdoor for remote access. Changes to the Windows Registry, virus infiltration, and security software disabling commonly occur.
How does UNP Campaign Manager infect systems?
The trojan spreads through spam emails containing malicious attachments and deceptive advertisements. Fake Flash Player updates downloaded from suspicious sources commonly deliver the infection. Various file formats like Word documents, archives, PDFs, and executables with macros can carry the malware payload.
Email subjects are disguised to appear legitimate when the sender appears to be a well-known company or service. Enabling macros in suspicious documents triggers malicious script execution and malware installation.
What executable files are associated with this trojan?
The primary files include UNP.exe and UNPCampaignManager.exe which launch the malicious payload. Additional associated files include hideaway.exe, websteroidsservice.exe, host32.exe, msupdate.exe, camtray.exe, UNPUX.dll, and UNPUXLauncher.exe. These files work together to execute the trojan's malicious functions.
Simply terminating the process in Task Manager will not permanently remove the infection because associated files continue to reactivate it. Professional anti-malware tools must detect and remove all related files.
Can I manually remove UNP Campaign Manager?
No, manual removal is not advisable. The trojan has complicated code that modifies system files and the Windows Registry, making it extremely difficult to restore everything manually.
Attempting to delete the executable manually leaves associated files, processes, and registry changes behind. The malware can reactivate from remaining files, making complete removal through manual methods nearly impossible. Professional anti-malware software designed to fight malware is essential for complete removal.
How do I remove UNP Campaign Manager?
Use reliable anti-malware software to perform a full system scan that automatically detects and removes all infection pieces. Reboot into Safe Mode with Networking before running the scan for better results.
The security program checks all system locations for malicious activities and corrupted files. Run system optimization or repair tools after removal to fix virus damage. System Restore can also help with trojan termination by reverting your computer to a previous state before infection.
How can I prevent UNP Campaign Manager infection?
Never enable content or macros in documents from unknown senders. Verify email senders before downloading attachments or clicking links. Download Flash Player only from official Adobe websites, never from suspicious sources.
Be cautious with emails claiming to be from legitimate companies, especially those urging immediate action. Maintain updated anti-malware software and run regular scans. Avoid downloading files from unreliable sources or clicking suspicious advertisements.
Will Fortect remove UNP Campaign Manager?
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 UNP Campaign Manager, 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.
