I went to the quarantine, where it SAID the "threat" was, and there is nothing there, but every fifteen minutes or so it just keeps popping up that my rainmeter is a threat and that it's been quarantined.

Popup from AVG

Dakota,

Thank you for the screenshot. In this case, we request you to add that file to the exception list, go to AVG Zen -> antivirus -> Menu at the top right -> Settings -> General -> Exceptions and all that application to the list.

You can also report a false detection using this link: https://secure.avg.com/submit-sample. We are here, if you  need further assistance.

Dakota. Sorry to hear that. Please submit the particular application for analysis through https://secure.avg.com/submit-sample. Our developers will check this and help you further.

Still does it even after adding an exception.

Dakota, For your info, just in case that you are unaware, you can post the screenshot here in your topic. Click on 'Answer' & then click on the 'Image' [mountain symbol] & follow the instructions.
