In the last four weeks, I've seen a pop-up window with the message: "There was an error executing a required program. This program may be corrupt." and the address bar shows a file in my temp folder (currently: C:\Users\name\AppData\Local\Temp\cks3550.tmp). The strange thing is this always shows a different .tmp file. This has probably happened 2 or 3 times in the last month. I click 'OK' and nothing happens. Nothing stops ...no crashes. I have a relatively new Dell XPS 8700 running Windows Pro and I've had Malwarebytes installed from the very beginning and my scans have been clean. Google and Bing searches turn up nothing when searching for cks3550.tmp . Anyone ever see anything like this?
