I posted this in December, will post again. Intuit support does not know how to fix anything. This is a virus, plain and simple. It is designed to bug you into calling the fake support number and give them money. No quickbooks repairs will fix this issue. The fix is this:
Delete these files:
In folder: C:\Users\Public\Documents\Windows
90s.rtf
err.html
IntuitDownloadManager.exe
msg.ini
Newtonsoft.Json.dll
QuickBooksDownloader.exe
Sv.ini
Win32_API.dll
The other thing I'll add is there are tasks in the task scheduler to run the exe in that folder. Since the exe has been deleted (if you delete those files in c:\users\public\documents\windows) it cannot call anything to run, but it is still best practice to delete those scheduled tasks.
