Can a dll File Contain a Virus? The truth

The skilled forensic investigator, though, can still find traces of evidence of those storage devices within the registry, if they know where to look. The key below lists all the services that set to start at system startup.

  • I signed up for the single purpose of asking this question that i never hear asked or if it is it does not remain visible.
  • There’s a very good chance that the reason your Registry Editor was blocked is because you have a virus or other malware infection.
  • The System File Checker is the tool from Windows itself that can be used to replace/fix missing or corrupted system files.
  • Abbreviated HKCR, HKEY_CLASSES_ROOT stores information about registered applications, such as file associations and OLE Object Class IDs, tying them to the applications used to handle these items.

It should not be disabled, as doing so could cause problems with your system. Additionally, make sure that you’re running a reputable antivirus program to protect your system from malware that may try to disguise itself as dllhost.exe. A lot of times many software are developed to run on the older version of the Windows, so it may require a specific version of the Windows to run the DLL files.

Registry locations

Because the Windows registry controls important configuration settings on your computer, you shouldn’t try to access or edit it without knowing exactly what you’re doing. Thanks for that – the problem I face is that if I am an administrator and I want to change the permissions on a key that has Administrators as READ – it will say access denied….really annoying. I will try the powershell thing out and come back. System is also Read so can’t use psexec to do it. I am trying to edit this registry key via the command line – been searching around for ages but can’t find anything.

Optionally, once you’re successfully logged on to your user account, load the Registry Editor and you’ll see that the value you modified offline is reflected there. The Load Hive… option would be available if you’re currently in HKEY_USERS or HKEY_LOCAL_MACHINE. In this case, we select HKEY_USERS, and click the Load Hive.. The next job is to find the drive letter of your Windows installation, as seen from Windows RE. This can be done by running the BCDEDIT command. Even if you manage to launch Command Prompt using the Shift + F10 key combination or clicking the “Skip this drive” option, you won’t be able to access the encrypted drive. You’ll be asked to unlock the drive via Control Panel. You can delete this key if you change your mind, or temporarily allow the Registry Editor to run by changing the Value data back to 0.

The key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Fonts contains information about all the installed TrueType fonts. The value names are the font name as it is displayed, and the value data is the filename (and path if the font file is not in \Windows\Fonts). Knowing this you can change the names of fonts, get Windows to ignore a font by deleting its entry or relocate your font files by editing the path. But be careful, because invalid font entries can cause problems for Windows. Comparing the data that can be accessed from the Folder Options dialog box with the corresponding registry entries may help gain a clearer understanding of how it all works. It’s easier and safer to use this dialog box to manage the file type associations on your system, but sometimes a problem may occur for which the Registry Editor offers the only hope of a solution.

Although it’s useful, I find the existence of such a feature in a troubleshooting tool like the Registry Editor to be more than a little eerie. The REG_DWORD_BIGENDIAN type is a variant of the DWORD type, where the bytes are in a different order. Unless you’re a programmer, you’ll want to stay away from these types of DWORD values.

If you’re unsure, you can always do a search in Google on the dll file name. Here is a manual way of identifying DLL files in rundll32.exe. Open a Command Prompt by pressing WinKey+R and type cmd. Then type or paste the command below into the prompt and hit Enter. The simplest way to stop this message is in MSE is to go to the Settings tab and add the dll file or its folder to the list of Excluded Files and Locations.
