Fix Instup.exe high CPU issue now!

nstup.exe leads to high CPU usage

In this article you will find out:

  • how to deal with this issue
  • how to protect your data

Are you ready? Let's read!

Instup.exe is a component of Avast's antivirus software and is required to update the application. It is downloaded to your computer along with other files when you install the antivirus. In other words, it is a legitimate file that should not harm your computer. However, this is not the case and many users complain that the instup.exe file causes performance problems in Windows, namely, x up to 100% of the CPU resources. This, in turn, makes the applications unusable and makes it difficult to use the computer as a whole. This article will save you from this problem and will clearly show you how to prevent the file from affecting computer performance.

About this process

Instup.exe is the "Avast Antivirus Installer". This process installs the antivirus software. This file then helps keep virus definitions up to date and thus keeps Avast up to date on your device. The program runs in the background only during the installation of virus definitions and software updates. Thus, it practically does not consume system resources.

However, there is evidence that Avast updates its virus definitions more than 100 times a day, as it uses "Streaming Update" technology to immediately send updates to users.

Therefore, you can find the program file instup.exe in the cc manager and it can consume a certain amount of CPU resources.

To determine the authenticity of the Instup.exe file, you need to verify its location and digital signature. This can be done as follows:

Open the task manager, go to the Details tab and find instup.exe there. Right-click the file and choose Open File Location (repeat these steps for all instances in Task Manager). The file must be located in the following folder: C: \ Program Files \ Avast Software \ Avast \ setup.

Any other location of the file indicates that it is not a genuine file, but a malicious copy.

Next, you should check the digital signature of the instup.exe file:

In the task manager, select the file instup.exe with the right mouse button and click on the "Properties" button. Next, select Digital Signatures: the Signer Name column should be Avast Software sro.

If the file was not signed by Avast, it is a malicious copy and you should delete the file from your computer, and then run any other virus or malware scanner.

Instup.exe high CPU usage fix


Stop the process through Task Manager

If the instup.exe process is using a lot of resources, you can simply force it to stop using the Task Manager.

On the Details tab, select the instup.exe file and click the End Task button. The problem should now be resolved and the performance of the computer should be improved.

Restart PC

If the process continues to run in the background, try to restart the computer. After that open Task Manager and check if instup.exe is using computer resources.

Avast antivirus may have been corrupted for some reason. You can use the built-in troubleshooter to initiate a self-repair program.

To do this, you must start Avast, open the menu and go to "Settings". Next, click on "Troubleshoot" and then select the "Repair Application" button.

After a few minutes, the repair will complete - this should stop instup.exe from continuously running in the background.

Since Instup.exe may run in the background, an error may occur when installing the update. After that, the Avast antivirus installer will continue to retry installation attempts, and this will inevitably lead to high disk usage.

Therefore, try disabling automatic Avast updates and see if that fixes your problem.

To disable automatic program updates, open the Avast settings menu, select the General tab. Then select the "Update" option, go to the "Virus definitions" section, and select "Manual update". Then go to the Application Update section and also select Manual Update. After that, you should restart your computer and re-enter the Task Manager to check the disk load.

Protect all stored data, or at least those data that are important to you

Of course, you can reinstall the operating system in order to forget about the system errors and other computer problems that arise. However, before doing this, you should protect all stored data, or at least those data that are important to you. If you do not do this, you will lose all the contents of the hard drive. Therefore, we will deal with information recovery.
