That call was indeed an obvious scam. Good thing you hung up. The caller was not able to do anything with your computer. Be aware that they gain access only with the use of a computer-sharing tool such as Teamviewer and if you downloaded it on your PC.
And that strange file you found on your dekstop, you probably got that from somewhere else. If your not familiar about what the file was for, do not delete it. Refer the issue to a local technician instead so you get the most accurate response.
