So you are using your computer when an update window takes over the screen, starts counting down, and refuses to close. That is the first major warning sign. Real updates generally identify the program and let you control what happens next.
The name Application Update Virus does not point to one piece of malware. It is a general label for suspicious behavior that may come from unwanted software, a misleading website, browser notification abuse, or another hidden process displaying a fake maintenance message.
Now here is the important part: do not trust the buttons simply because they look normal. Clicking the panel or accepting its download could lead, similar to Moo Virus Link, to unwanted programs, browser redirects, intrusive advertisements, stolen information, or additional malware, especially if browsers open or search by themselves.
We tested that SpyHunter successfully removes "Application Update"* and we recommend using it. It will block "Application Update" from reinstalling itself and it will make sure your device is clean from any malware.

The guide below explains how to find and remove the cause safely. If manual troubleshooting feels complicated, SpyHunter 5 can scan the system for unwanted programs and viruses, remove detected threats, and help confirm whether the fake update prompt has stopped appearing.
“Application Update” Removal Guide
Start with the quick removal method below before moving to the full guide. It checks the most common places where “Application Update” may appear and can sometimes solve the issue without deeper system work. If the threat returns or anything looks unresolved, continue with the advanced steps that follow.
Quick Manual Removal for “Application Update” – Try This First
- 1.1First, go to your downloads folder (This PC > Downloads), sort the items there by date, and see if any suspicious files have been downloaded recently. Found anything fishy? Delete it before continuing.
- 1.2Next, go to the Start Menu, navigate to Settings (the gear icon), and then to Apps.
- 1.3You’ll see all installed programs listed on that page – sort them by installation date and look for “Application Update” or anything else that looks suspicious, unfamiliar, or unwanted.
- 1.4If you find “Application Update” or another sketchy app, select it and start the uninstallation process. Be careful when following the uninstallation prompts so that you don’t let anything linked to the program remain on your PC.
-
1.5Afterward, look for the installation directory. You’ll often find it at
C:\UserNames\UserName\AppData\Local\Programs\, but it might also be elsewhere. - 1.6If you find the malware folder, remove it together with any leftover files that might still be in it.
Restart the computer and check whether the unwanted app or process is still present. If “Application Update” appears again, do not treat that as a failed cleanup – Trojans often rely on hidden leftovers. Continue with the fuller removal instructions below.
SUMMARY:

Preparatory Steps for Removing “Application Update”
Before you continue with the hands-on cleanup, prepare Windows so hidden items are visible and locked files can be removed. “Application Update” may protect some of its components while they are active, so these two setup actions help you avoid errors in the later steps.
1. Preparing for the “Application Update” Removal
- 1.2Next, you’ll need to download and install a free utility called LockHunter It’s crucial because it lets you delete files locked by malicious processes.
We know some users prefer not to add extra software and would rather complete every step manually. In this case, the utility is included because certain malicious files may stay locked while “Application Update”-related processes are still active.
LockHunter is free to use, does not require an account, and should take only a short time to install. Keep it available while you remove folders that Windows refuses to delete normally.
Remove “Application Update” Processes From the Task Manager
Next, inspect Task Manager for processes that do not belong on the system. The name used by “Application Update” can differ between infections, so rely on behavior, location, resource use, and your own judgment instead of searching for one exact process name.
2. How to Delete “Application Update” Processes in the Task Manager
-
2.1This is done through the Task Manager which you can open by pressing
Ctrl + Shift + Esc. - 2.2If it shows a simplified view, click More Details to expand it and see all running processes.
- 2.3Sort the list of processes by how much Memory or CPU they are using. Then look out for any that are using unusually large amounts of either resource type and yet don’t seem related to any legitimate programs that you have on your PC.
Note: Don’t expect to find a rogue process named ““Application Update”“. Most forms of malware will hide their processes under innocent-looking names.
- 2.4For each dubious process, right-click it and select Open file location. This will lead you to a folder where the data used by this process is stored.
- 2.5You must delete that entire folder, but you’ll likely get an error when you attempt to do that because some of the files there are in use by the malware. The workaround is to use LockHunter: right-click the folder, select “What’s locking this folder?” from the context menu, and click Delete in the next window.
- 2.6After removing the files, go back to Task Manager, write down the name of the rogue process (you’ll need it later), then click it, and click the End Task button to quit it.
Delete “Application Update” Virus Files
The remaining cleanup requires checking several folders because “Application Update” may leave helper files in startup, program, profile, and temporary directories. Search carefully and do not assume there is only one malware folder – Trojans often spread components across multiple system locations.
3. How to Get Rid of “Application Update” Files
-
3.1Start by examining the Startup folders at:
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartupC:\Users\*Your Username*\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup -
3.2Search them for suspicious files, but if you aren’t what files are rogue, just delete everything in those folders except for the
desktop.inifile, which is a standard system file. -
3.3Next, inspect the
Program FilesandProgram Files (x86)in yourC:drive. Some malware apps will create folders there, so look for anything that looks linked to “Application Update” or that is otherwise unrecognized or out-of-place folders. Delete anything suspicious you may find. -
3.4Three other locations you must check are:
C:\Users\%user%\AppData\Local\C:\Users\%user%\AppData\Local\Programs\C:\Users\%user%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\
Again, if you notice anything fishy in them, it must be deleted. And if there’s a folder you aren’t sure about, it’s probably best to get rid of it. At worst, it will be something harmless linked to a legitimate program in your system. However, if you didn’t recognize its name right away, chances are it’s something you either don’t need or something that’s outright unwanted (like “Application Update”). -
3.5Finally, remember to clear the Temp folder. It’s located at
C:\Users\YourUsername\AppData\Local\Temp.
It stores only temporary files, which are all okay to delete. So, to save yourself some time spent looking for malware files, just Ctrl + A to select everything, and then press Delete from your keyboard to delete all of the folder’s contents.
Get Rid of “Application Update” Scheduled Tasks
Task Scheduler is easy to overlook, but it can keep a Trojan active after files are deleted. A leftover scheduled task may launch “Application Update” again, reinstall a removed component, or call another script, so review these entries carefully before finishing the manual cleanup.
4. Eliminate “Application Update” Scheduled Tasks
-
4.2For each task, double-click it and open the Actions tab, where you can learn what it is that the task is set to perform. Look for tasks that run unfamiliar executables, scripts, or anything located in the
AppDataorRoamingdirectories. - 4.3If you come across a task that executes anything suspicious, write down its file path, then right-click the task, and select Delete.
- 4.4After that, go to the file path you saved and delete the file that the task was set to run.
Uninstall the “Application Update” Malware App Through the Windows Registry
Registry cleanup matters because startup values and service entries can relaunch “Application Update” after a reboot. Work slowly here, because deleting the wrong value may affect Windows or installed software. If you are not comfortable editing the registry, use SpyHunter 5 as the safer option.
5. Remove “Application Update” Through the Registry
- 5.1Type “regedit” in the Start Menu and hit Enter to go to the Registry Editor.
- 5.2Then click Edit > Find to open the search box and then type the exact name of whatever program you tried to uninstall during the quick steps at the start of the guide.
- 5.3Click Find Next and if a result comes up, click the registry key (folder) in the left panel that contains it and delete that key. Perform another search after each deleted key until there are no more results for that search query.
- 5.4Next, search for the name of any other programs you attempted to delete. Also search for the names of processes you ended in the Task Manager earlier in the guide.
-
5.5After you’ve deleted all relevant entries, manually navigate to these registry keys:
HKCU\Software\Microsoft\Windows\CurrentVersion\RunHKCU\Software\Microsoft\Windows\CurrentVersion\RunOnceHKLM\Software\Microsoft\Windows\CurrentVersion\RunHKLM\Software\Microsoft\Windows\CurrentVersion\RunOnceHKLM\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\RunHKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\RunHKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesHKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesOnceHKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce\SetupHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services - 5.6Select each of these keys to reveal their contents in the right panel. Then look for values referencing “Application Update” or any unknown applications. Delete only the specific values linked to the malware and leave the keys that contain them intact.
