Incomprehensible Error Message

I keep getting an error message (cf. attached image) on my PC. I have no idea to which software it is referring. In the top right hand corner of the message is a 'X' which you would click on to close it; however, it will not close. I have tried opening Task Manager to see if that can tell me what it is. That does not work. Even though I cannot close the error message by clicking on the 'X', as soon as I do anything else, try to open Task Manager or to open any app, or to open a file, etc. it simply goes away. It is also intermittent. Some days I get it several times and then I got it this evening for the first time in over a week.

I have scanned my PC using the following applications. In each case I used the current version and the databases are up-to-date. Of the ones in the following list I only have Comodo providing real time protection.They are COMODO Internet Security Premium, Malwarebytes ANTI-MALWARE and SUPERAntiSpyware. They all reported no threats were found.

I would like to know what can be the cause of this error message. If no one recognises it I would appreciate ideas on how I could find out what it is. It would be good to know how to solve this issue.

You need to take a screenshot of such a message again (using +alt+prt scr so ONLY that window shows) and then you need to look at the resulting image yourself first before attaching it here, so the message does actually show.
