Many anti-virus scanners have marked this application as a Potentially Unwanted Program, and while Boost My PC is not so harmful on its own, it comes bundled with other Potentially Unwanted Programs that might harm your computer.

About Potentially Unwanted Applications

If you’ve ever downloaded and installed a software package via the internet (shareware, freeware, etc,), odds are high you’ve unwittingly installed unwanted programs on your computer. Potentially Unwanted Programs (PUP), also referred to as Potentially Unwanted Applications (PUA), are programs that you never wanted in the first place and sometimes come bundled with freeware software. Once installed, most of these applications can be hard to remove and become more of a pain rather than a benefit. It’s clear by the name – unwanted applications – but did not really constitute “malware” in the traditional sense. Much like malware, PUPs create problems when downloaded and installed on your machine, but what makes a PUP different is that you grant consent to download it – though the truth is vastly different – the software installation bundle actually tricks you into agreeing to the installation. Regardless of whether it is considered malware or otherwise, PUPs are almost always detrimental to the user as they could bring on adware, spyware, keystroke logging, along other dangerous “crapware” features on your computer.

Exactly how do unwanted programs look like?

Potentially Unwanted Programs appear in different forms and varieties, however, most times, these are typically adware programs that show annoying pop-up adverts and advertisements on web pages you drop by. PUPs that come as browser add-ons and toolbars are widely identifiable. These toolbars change your homepage and your search engine in the installed web browser, track your web activities, influence your search results with redirects and sponsored links, and eventually slow down your web browser and diminish your browsing experience. PUPs lie inside the gray part of the software spectrum. They may carry keyloggers, dialers, along with other software built right into them that might monitor you or send out your sensitive information to 3rd parties. Even if the PUPs aren’t inherently malicious, these programs still do practically nothing good on your personal computer – they will take valuable resources, slow your PC, weaken your device’s security, making your PC more susceptible to malware.

Tips on protecting yourself from PUPs

• Read the EULA carefully. Look for clauses that say that you ought to accept advertising and pop-ups or bundled programs from the company. • Choose the “custom” install whenever downloading a program. In particular, look closely at those tiny boxes that have been checked as default, where you might ‘agree’ to receive ads or install software bundlers. • Use an ad blocker/pop-up blocker; Deploy anti-malware products such as Safebytes Anti-malware. These types of applications will establish a wall between the computer and cybercriminals. • Avoid installing freeware software you will not make use of. Avoid installing browser extensions and applications you aren’t knowledgeable about. • Only download software from the original providers’ sites. Stay away from download portals because they use their own download manager to pack additional programs together with the initial download.

What you can do if Malware Prevents You From Downloading Anything?

Malware could cause all sorts of damage after they invade your system, from stealing your private details to deleting files on your computer system. Certain malware types alter web browser settings by including a proxy server or change the computer’s DNS configuration settings. In these cases, you’ll be unable to visit certain or all websites, and therefore unable to download or install the required security software to remove the infection. So what you should do if malicious software prevents you from downloading or installing Anti-Malware? Even though this kind of problem can be difficult to get around, there are a few steps you can take.

Download the application in Safe Mode with Networking

If any virus is set to run immediately when Windows starts, stepping into safe mode could block this attempt.

Now, use your internet browser normally and navigate to https://safebytes.com/products/anti-malware/ to download and install Safebytes Anti-Malware. 4) Immediately after installation, run a full scan and let the software remove the threats it discovers.

Switch over to a different web browser

Some malware only targets specific web browsers. If this sounds like your situation, employ another web browser as it may circumvent the computer virus. If you’re not able to download the security software using Internet Explorer, this means the virus may be targeting IE’s vulnerabilities. Here, you must switch to another internet browser like Chrome or Firefox to download the Safebytes program.

Install and run anti-virus from a USB drive

This kind of error could be caused by several factors. It could be due to your antivirus program or other third-party programs installed on your computer. It is also possible that the installation of the Microsoft .NET framework id corrupted or some of its installation files are corrupted. Thus, to fix the error, there are a few suggestions you need to follow such as:

Option 1 – Try to temporarily disable your anti-virus program

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed on your computer. Thus, disabling them or any security software installed in your computer is always a good idea you can try when you’re not able to access the shared drive in your computer. There are times when you encounter problems like the “Unhandled exception has occurred in your application” error due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program in the meantime and check if it fixes the error or not.

Option 2 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Once your computer has restarted, check if the error is now gone. If it is, then the culprit is some third-party program. Thus, you have to enable the third-party programs one by one to find out which one of them is causing the the “Unhandled exception has occurred in your application” error.

Option 3 – Try to run a System File Checker scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be the cause why you’re getting the “Unhandled exception has occurred in your application” error. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Now restart your computer and see if the problem is fixed or not.

Option 4 – Install and update Dependencies

There are times when programs and applications need to have drivers and supporting software installed for them to properly work. Although the installation usually takes care of it, it’s time for you to do some manual check especially if you are getting this issue of abnormal program termination.

• Install some qualified drivers – A number of high-end games and applications need to have correct and valid drivers for them to work. They just don’t work with general drivers though. Microsoft has this Windows Hardware Quality Labs testing also known as WHQL testing which makes sure that drivers meet the correct experience and pass through the proper testing before certification. Thus, when installing drivers, you need to ensure that they are qualified drivers for your Windows 10 PC.
• Download and install or Update DirectX – As you know, Microsoft DirectX is a suite of technologies developed by Microsoft to provide hardware acceleration for heavy multimedia applications like HD videos and 3D games. Since you are using Windows 10, you have the DirectX 12 version while the earlier Windows versions use the DirectX 11 version.
• Install the Microsoft DirectX End-user runtime – The Microsoft DirectX end-user runtime gives updates to version 9.0c as well as previous versions of DirectX. To install it, click on this link and download it.
• Update or install the .NET framework – The .NET framework is used by games and applications during development which means that without the runtime files that are installed in your computer, it definitely won’t work. Thus, you need to install or update this framework. You can also use the .NET setup verification tool to verify it.

As you know, the Windows Update process takes compatibility seriously. The Windows Updates need to be compatible with the hardware as well as all the installed applications in the computer else the Windows Updates will only get stuck in the process. Two of the Windows 10 errors that shows up during this case is the error 0xC1900208, 0x4000C. These error codes are caused by incompatible applications which means that there might be an incompatible app installed in your computer that’s blocking the upgrade process and prevents it from finishing. That’s why you need to make sure that all the applications on your computer are updated to their latest versions and then check the compatibility. So if there are any incompatible apps, be sure to uninstall them and then try doing the upgrade once again. Take note that these error codes are just among many compatibility issues that the Windows Update throws up. Since the error is caused by a compatibility issue, you have three options – first, you can update the incompatible application to the latest version, second, uninstall the application or trick Windows and make it seem like it’s compatible.

Option 1 – Try updating the application or software

As mentioned, you can try updating the concerned application or software to its latest version to resolve the compatibility issue and in turn, fix the errors 0xC1900208 – 0x4000C. Note that depending on where you had installed the application, your steps will change. So if you have it installed directly from the website, refer to these steps:

• Look for the built-in option to check the updates since the most application has this option.
• You also have the option to go to the website of the application and check if there is a new version available. If there is, download and update the app.

On the other hand, if you have downloaded the app from the Microsoft Store, here’s what you have to do:

• Open the Store and click on the three dots located at the top-right of the window.
• Next, click the Download and Updates option.
• From there, check if there is an update available for the store. If there is, update it.

Option 2 – Try to uninstall the application or software

If updating the app or software to its latest version didn’t help and you’re still getting the error 0xC1900208 – 0x4000C every time you attempt to install the Windows Updates, you may have to uninstall it. You will need to use the usual Program and Features to uninstall it if you have downloaded it from the website.

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 3 – Try bypassing the Upgrade Advisor

There are times when a software developer fails to pass the compatibility test for their apps. It could be that they work on Windows 10 upgraded version but just didn’t pass the compatibility check. So if you are pretty certain that the app really works on Windows 10, you can just bypass the Upgrade Advisor.

If you were trying to update your Windows 10 computer and failed due to Error Code 0x80240438, then you’ve come to the right place as this post will give you a couple of suggestions you can check out to resolve this error. You can encounter Error Code 0x80240438 not just in Windows Updates but also in Microsoft Store. This is due to the fact that the delivery mechanism for both Windows Updates and Microsoft Store is common and interdependent. This is why a lot of Windows Update and Microsoft Store error codes are similar. And so fixing them won’t be that hard as well since most methods are basically the same. When you encounter this kind of error in Windows Update or Microsoft Store, you will see the following error message on your screen:

“There were some problems installing updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help – (0x80240438).”

To resolve Error Code 0x80240438, here are some potential fixes you need to check out:

Option 1 – Try to run the Windows Update Troubleshooter

The Windows 10 Store Apps Troubleshooter will help you in fixing the Error Code 0x80240438. This is a great built-in tool from Microsoft that helps users fix any app installation issues.

Option 2 – Try to temporarily disable anti-virus and Windows Defender Firewall

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed on your computer. Thus, disabling them or any security software installed in your computer is always a good idea you can try when you’re not able to access the shared drive on your computer. There are times when you encounter problems like Error Code 0x80240438 due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program and Windows Defender Firewall for the meantime and check if it fixes the error or not.

Option 3 – Disable the Proxy server

You can also try to disable the Proxy server for your LAN to fix Error Code 0x80240438 especially if your computer was attacked by some malware or adware recently. In such cases, there is a chance that the malware or adware has changed your network settings in order to generate intrusive advertisements. Thus, you have to disable the proxy server and you can do that by following these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 4 – Try modifying the “Remove access to use all the Windows Update features” Policy

• Start by tapping the Win + R key combination to open the Run utility.
• Then type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• Once you’ve pulled up the Group Policy Editor, navigate to this setting: User Configuration > Administrative Templates > Windows Components > Windows Update
• Next, double click on the “Remove access to use all the Windows Update features” policy and set its radio button to “Not Configured”. As you can see, this policy setting has the following description:

“This setting allows you to remove access to Windows Update. If you enable this setting, all Windows Update features are removed. This includes blocking access to the Windows Update Web site at http://windowsupdate.microsoft.com, from the Windows Update hyperlink on the Start menu, and also on the Tools menu in Internet Explorer. Windows automatic updating is also disabled; you will neither be notified about nor will you receive critical updates from Windows Update. This setting also prevents Device Manager from automatically installing driver updates from the Windows Update Web site.”

If you enable this policy setting, you can configure one of the following notification options:

• 0 = Do not show any notifications: This setting will remove all access to Windows Update features, and no notifications will be shown.
• 1 = Show restart required notifications – This setting will show notifications about restarts that are required to complete an installation.
• Now you need to exit the Group Policy Editor and restart your computer for the changes to take effect.

Option 5 – Try resetting the Windows Update folders

Resetting the Windows Update folders can also help in fixing the error in both Windows Update and Microsoft Store. All you have to do is delete the contents in both the SoftwareDistribution folder and reset the Catroot2 folder as well.

Option 6 – Try downloading and installing the Windows Updates manually

Error Code 0x80240438 might be due to a Windows Update that has failed. So if it is not a feature update and only a cumulative update, you can download the Windows Update and install it manually. But first, you need to find out which update has failed, and to do so, refer to the following steps:

• Go to Settings and from there go to Update and Security > View Update History.
• Next, check which particular update has failed. Note that Updates that have failed to install will be displayed under the Status column which has a label of “Failed”.
• After that, go to the Microsoft Download Center and look for that update using its KB number and once you find it, download and then install it manually.

Note: You can also use the Microsoft Update Catalog, a service from Microsoft that provides a list of software updates that can be distributed over a corporate network. With the help of this service, it can be easier for you to find Microsoft software updates, drivers as well as fixes.

Error Causes

This error may result on your computer screen due to several reasons. Some of the most common underlying causes include:

• A leftover Registry Key
• Bad entries from previous Security Package
• INFCACHE.1 file corrupted

Further Information and Manual Repair

To successfully overcome this problem and ensure the successful installation of Kaspersky Internet Security software on your system, try the methods given below.

Method 1- Remove the Leftover Registry Key

Sometimes Internal error code 2771 may appear during installation due to the leftover registry key from the previous Kaspersky software removal. A registry key is often created when uninstalling the previous Kaspersky version from the PC. This key is left behind even after you reboot your system. This key is called AVP**_post_ uninstall, you need to delete it to ensure the new version of the Kaspersky program is installed successfully on your PC.  For this, simply go to the start menu and type Regedit in the search bar. Now navigate to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun and then look here for the registry key called AVP**_post_ uninstall. In order to delete this file, right-click it and then select delete. Once uninstalled, reboot your PC and then try installing the Kaspersky Internet Security program again. Hopefully, this will resolve the issue. If the software installs smoothly, then the error is fixed, in case it still persists, then try other methods illustrated below.

Method 2 - Remove the INFCAHCE.1  Corrupt File

Another reason for the error pop-up may be INFCAHCHE.1 corruption. This file is basically used to store driver information and inf file locations. However, if it contains corrupted information, then you must remove it. To do this, go to the start menu and type cmd into the search bar. This will open a command prompt. Here type del C:\Windows\infinfcache.1. Now reboot your PC and try installing Kaspersky software on again.
