Hello xolomn,
The file QtGui4.dll is a legitimate component of Adobe Photoshop Elements. Do you have Adobe Photoshop installed on your computer?
Do a search for the QtGui4.dll and then check the path of the file. It may be malware if not in the correct path for Adobe.
Download Microsoft Security Essentials and scan for malware from here. Or use any other virus scanner to check and verify your computer is not
infected.
You have installed several games that if downloaded may contain a virus.
Hope this helps.
Thanks,
Marilyn
