Quarantine issues

Windows 10 or 11 
  I've been working with Fidelity for many years and their tech support was not able to help me with an issue. The tech guy said I need to get into the quarantine and ask AVG for an exception to the item that the Quarantine caught.  
What happens is as soon as I log out I get " an unrecoverable error and the Fidelity app is removed from the task bar as well as the desktop.
Question #1 Where the hell do I find the goddamn Quarantine file?
Question  #2 Should I delete whatever is causing this problem even though there's no bugs found through AVG scans.

And bonus question  I bought this new HP back in November and AVG charged me for a new year without giving me a credit for the subscription I currently hava/had which expires in May this year.
