Constant threats

Hello Ed,
We're glad to help you.
Quarantine is a safe place in AVG AntiVirus for storing potentially harmful files and completely isolating them from the rest of your operating system. 
Once the file has been quarantined by AVG, it cannot be accessed or run by any outside processes, software applications, or viruses.
For more details, please refer to the below article. AVG blocks viruses, spyware, and other malicious threats. Additionally, it protects you and your data against dangerous fake websites, ransomware, and hackers in real time, however by default scan settings, it will not delete any files from your computer. If you would like to configure the scan setting to remove the threats, please refer the below article, check the steps provided under the Scan section to configure your AVG scan, according to your preference. Thank you.

For the last 3 weeks, whenever I come to my computer, AVG tells me that it found emails that were threats.  I then go to the quarantine and delete them.  Is there a way that I can set AVG to delete every threat instead of my having to work through them myself?
