Rola02, the explanation provided above by jumper-d-1981 is a pretty thorough review of how to address the issue involving a corrupted Intuit installation in which you get a pop-up advising you of a company file issue, with a number to contact Intuit support. It is a scam, but the fix is relatively simple. You can also go through the time and pain of contacting the legitimate Quicken Support folks but it will lead to the same outcome (delete the files in the referenced directory and restart QuickBooks).

Good Luck.
