7 Tools to Unlock Those Hard to Delete Files

3 November 2022 Windows

“It is a free tool to delete files blocked by something you do not know.” That is such awful English. Hopefully, It isn’t a sign of incompetence when it comes to file deletion programs. DeadLock is a free file and folder unlocking utility brought to you by CodeDead. It can help you unlock files or folders that you’re unable to delete, copy, rename or move. As of version 1.3, DeadLock can driversol.com/dll also take ownership of files and folders! IObit Unlocker is a light-weighted yet powerful tool designed to fix the “Cannot Delete” or “Access Denied” problems.

  • Virus total still shows it as a problem for 18 AV engines as of now.
  • The error “all download this file contained a virus and was deleted” means you have a ZeroAccess rootkit.
  • Select “Full Scan” and wait for the various files to be thoroughly checked to highlight the potential damaging virus.
  • I’m not entirely sure that the VTC on this was fair, or necessary.

I have successfully done this with the latest 21H2 build of Windows 11. Based on data we gathered from forums, some users managed to resolve “The action cannot be completed because the file is open in another program” message by turning Preview mode off. This is a useful, yet sometimes conflicting option offered by Windows to view the content of certain files prior to accessing them. It is easy to do and will not affect system performance in any way.

The data contains a key derivation function, PBKDF2-HMAC-SHA-1, a salt, and an encrypted data value, which we’ll call DATA_2. The encryption.userKey value is encrypted with Data Protection API , recognizable with the first constant ~60 bytes metadata. Decompiling is never going to give you the full picture. If you can’t find the source of the original then create a dll with a different name and include that in your application. The system flow is that when the user click the Generate Report button it calls the DLL as well as passing parameters needed by the DLL. However, the company added a new data to database so all of the computation for the New Plan Code is completely wrong.

DLL files are Microsoft’s property and each Windows OS comes pre-installed with these files. If it’s gets corrupted or mistakenly removed from the system you can’t find it on the Microsoft website. However, you can easily fix this problem just by installing missing .DLL files.

If all goes well, you’ll be able to debug the program in an easier and more convenient manner. There are two main places where DLL files can be found in Visual Studio. The DLL file is a resource file and is used to store data, such as a class library. The DLL file is a compiled version of the class library. Visual Studio also has features for adding new resources to a DLL file.

Finally, we create an execution thread in our process using CreateThread and the pointer to the memory region. After that this malicious dll file executes an exported API function, namely @YGXXZ (a.k.a HackCheck), which has customized decryption logic. This function runs this decryption loop and decrypts the encrypted string “klyjl8|tt8Pys.” by XORing logic then print that output string by OutputDebugStringA API call. This MSI file loads this malicious dll file[ main.dll] through regsvr32.exe with arguments being -n -i “install”. Regsvr32.exe is a command-line utility to register and unregister OLE controls, such as DLL files and ActiveX controls in the Windows Registry.

With this approach, there is no on-disk library or executable file with malicious code. It is all in the memory of the exploited process. But, the attacker may want a method of persistence after exploiting the process and may install additional forms of malware that store files or scripts. However, there have also been instances when JavaScript was used not just to download malicious software but also to write them. Malware are traditionally written in C and C++ but RAA, a type of ransomware, is special since it’s written in JavaScript.
