Total AV found and cleaned it, but now I can't get my Desktop version to open. So frustrating
Could be a false positive. Do you know what files were removed?
If you have not removed them from your Quarantined file try to restore them.
To get Quicken to work again, you will probably have to reinstall the program.
After you reinstall or restore see if you can download Malwarebytes free version is it flags Quicken,
I use Malwarebytes and Webroot AV neither flags Quicken (so far).
