Dwm.exe

Dwm.exe – a process that you can find running in the Task Manager section

Dwm.exe is a completely legitimate and safe process that you can find running in your Task Manager section.[1] All Windows computers come with this file that is also known as the Desktop Window Manager. Dwm.exe is a necessary component of Windows Vista, Windows 7, Windows 8 and Windows 10 systems and should not be removed, otherwise, some specific system struggles and problems might occur. Basically, this process belongs to the desktop graphical user interface and is responsible for enabling the Windows Aero graphical user interface and visual theme. In other words, it is responsible for the graphical effects, such as live window previews and a glass-like frame around windows. However, some cybercriminals might come up with ways to misuse the name of this file and this is the main reason why some users called it Dwm.exe virus.

Users often confuse the legitimate Dwm.exe file with the malicious one as the original uses lots of memory space. However, this is necessary due to the process's operating technique. If you find the Dwm.exe process running only in the Task Manager, we can assure you that nothing rogue is going on and everything is at it is supposed to be. However, if you overcome multiple files with the same name running in different locations, that might be a signal of something truly hazardous.

You can find out the if file is truly a malicious version by performing a full system scan with Reimage. If the program detects that the process is malware-related, you need to take actions to remove Dwm.exe permanently. However, you need to be very careful while proceeding with the elimination as you can accidentally terminate the legitimate process which might cause you some problems in the future.

Furthermore, note that the legitimate version of Dwm.exe can be found in the C:\Windows\System32 folder. If the file is in any other location, there is a big chance that it is a malicious version. You need to take actions ASAP, otherwise, the hazardous process might cause such consequences:

  • injection of other infections;
  • data theft;
  • CPU[2] and GPU overuse;
  • software struggles;
  • etc.

Remove Dwm.exe virus from your computer system to avoid such possible unwanted consequences. Moreover, keep on reading to learn all precautionary measures that you can take to prevent secret malware infiltration.

Malicious files can appear on the PC in different ways

Normally, legitimate computer files come with the installed operating system. However, as we have already mentioned, malware may be hiding in your system under an identical title. So, where do these malicious files come from? Well, you might accidentally install malware-related processes by opening dubious email letters and their attachments. This is why you should always be careful while opening your inbox and identifying the sender.

Moreover, avoid clicking on dubious-looking pop-ups[3] or links that you overcome online. Rogue components might be injected into these links and related in an installation of malware. Additionally, keep all of you programs updated, so that they would not include any outdated components. Last but not least, we recommend downloading and installing reliable antivirus software. Do not hesitate to invest a truly reliable one as these programs appear to be truly helpful and take care of the system all the time.

Remove the malicious Dwm.exe process 

We do not recommend deleting or stopping the original version of the file. If you do so, your system might start struggling and your programs might crash. However, if you have used reputable tools and they have detected that the process is malicious, you should remove Dwm.exe virus ASAP. Remember that there cannot be two processes running in the system with the exact same name.

Furthermore, after you perform the Dwm.exe removal, you should search the system for any harmful “leftovers”. We advice using tools such as Reimage, Malwarebytes MalwarebytesCombo Cleaner, or Plumbytes Anti-MalwareMalwarebytes Malwarebytes. Moreover, refresh the entire system to ensure that all malware[4] traces are gone. Additionally, memorize all malware avoiding steps as they might be very helpful in the future and let you avoid similar problems.
