KERNEL.32dll

[Leo24]

Please be informed that after performance enhancement of my Latitude E5540 (Win 7 Pro) by one of your tools (PC Speed up) recently in Oct 2024, the following announcement pops up:

AD Notification Manager.exe
Entry Point Not Found
The Procedure Entry Point 
GePackage Family Name
Could Not Be Located in
the Dynamic Link Library
KERNEL.32dll

[Larry Guy]

oh no! They're going for the kernel

[Wesly.Zhang]

Hello,

What kind of question are you trying to respond to? I don't understand the meaning of your post.

KERNEL.32dll, this file is not a system file, the system file should be kernel32.dll. Usually it is a library file at the core of  system (Windows NT BASE API Client). Its functions lie in the registry manipulation API, file manipulation API, window manipulation API, etc.

Regards.

[Leo24]

Mea culpa... "kernel32.dll ... Entry Point Not Found" announcement pops up - following registry optimisation by your tools - recently in Oct 2024. Hence your intervention would be much appreciated...

[Wesly.Zhang]

Hello,

There is no possibility of any error in this file, you need to check whether the file has been illegally modified and whether there is any malicious program activity on your computer.

First, you should check the file has not been modified. Run the following command:

Quote

Get-AuthenticodeSignature -FilePath "C:\WINDOWS\SYSTEM32\kernel32.dll"

The return result should look like this.

Secondly, You need to check if the kernel32.dll is located in "C:\WINDOWS\SYSTEM32“ directory A, because some malicious programs will generate a file with the same name in a different directory. It is a fake "kernel32.dll".

Reply the result here.

Regards.

 

Also, You can send a screenshot of the error here, and let's see which program loads the kernel32.dll error. Maybe you can tell us which program you run when this error appears.

Sorry I'm not a computer savvy. PowerShell download failed ... for Win 7 Pro. Anyway, it far beyond my competence.

"Maybe you can tell us which program you run when this error appears"

•Please be informed that during download pdf articles, such announcement ..."kernel32.dll ... Entry Point Not Found"... popped up twice on two separate occasions. Also such announcement popped up, while using Pdf Creator, within an attempt to "print" the selected article.

Moreover, Acrobat Reader DC version 22.3.20314.0 used to freeze for ~ 10 seconds after file opening. So, it was uninstalled and replaced with the earlier AdbeRdr11010. 

 

"whether there is any malicious program activity on your computer"

•In fact, Internet drop-outs persisted for some time! Ten minutes after starting Internet session and then variously. As I was about to finish and while checking Wireless Network Connection Status, often interruption occurred.

• "You can send a screenshot of the error here"

Sadly, I failed to figure it out on my Latitude E5540 (Win 7 Pro), while using Fn + Print Scr keys. Possibly, due to the planned obsolescence by Dell. Consequently, some keyboard keys didn't work, yet the numeric pad numbers functioned OK.

Hello, @Leo24

OK, I got it. Could you send kernel32.dll to https://opentip.kaspersky.com/ and tell us Whether the file is clean or in any state.

Regards.

Hello, @Leo24

Received, then there is no problem with the file itself, so let's investigate who loaded this file and made the error. We may need to try to find some clues in the Windows logs. We need to get here.

Start by pressing the Win + R keys on your keyboard.

Second, in the pop-up Run window, type: eventvwr.msc and press Enter.

Check the opened System Event Viewer for anything about the kernel32.dll error and see if there is any mention of the process that went wrong.

We are waiting for your reply if you find relevant content.

Regards.
