It’s not a virus (it’s much too large to be legitimate malware which tries to be small to avoid detection). Moreover, DVDMaker is the Microsoft program for making and using DVDs. It is included with Windows and can be removed via the Windows components dialog. You can access it in two ways:
- Control Panel:
- Open the Programs and Features Control Panel applet
- Click Turn Windows features on or off:
Now uncheck Windows DVD Maker from the Media Features branch and click
If it were a virus, the problem would be one of two things:
- Files are in use
- Insufficient permissions
Files in use
Dealing with in-use files requires two steps:
- Determine the source of the files in use
- Unlock the files or determine the source of the execution and stop it
Determine the lock
This is simple enough; just a program like Unlocker and run it on the files or folder to find out what programs (executable files) are locking the file(s).
Unlock the files
This is equally simple; just click Unlock All in the Unlocker dialog. You should now be able to delete the previously locked files.
One warning though: depending on what is locking it (e.g., a driver), it may not be possible to unlock it or worse, may crash the computer, so you will want to use the next step instead.
Determine the source of execution
It is more advisable to find where/how the executable that is locking the files is being run and stop it. This can be done with tools like Autoruns. Just look for the executable that you saw in Unlocker and disable (and later on, delete) it.
Then reboot, and now the program/driver/etc. should not be running, which leaves the target files unlocked and deleteable.
The error displayed in your screenshot clearly indicates that the files are only write-accessible by TrustedInstaller which is a virtual user account used by Windows for updates and such (which is normal for Windows components).
You will need to add yourself to the permissions of the file(s)/folder(s) in question. You can do this via the Security tab of their Properties dialog(s):
Since it is owned by TrustedInstaller, you will first need to take ownership before adding permissions. This is done through the Advanced button. It may be easier to do it from the command-line instead:
- Open an elevated command-prompt (Start⇨
cmd.exe then either press Ctrl+Shift+Enter or right-click and select Run as Administrator)
Change to the correct folder, for example:
cd "C:\Program Files\DVDMaker"
takeown /r /f .
icacls . /grant everyone:f /t
rd /s /q "DVDMaker"
