AVG spam quarantine when Outlook opens

I'm currently using the free version:
Build number: 1.191.3.4720
AVG Antivirus Free version: 17.4.3014
AVG Framework version: 1.203.3.5167
AVG Setup version: 1.203.3.5167

and I've recently noticed a problem. When I start outlook AVG starts spaming me with "Threat secured! We've safely locked this file in your quarantine." Things like "Win32:Trojan-gen", "JS:Downloader-DON [Trj]" or "Win32:Crypt-SKT [Trj]" are what AVG blocks. I've been scanning my computer with AVG, Ad-Aware, Spybot and CC-cleaner without being able to remove the source of this "outbreak" from AVG. Unsure of what to search for on the internet as well. Would be nice to get some assistance or guidance. Thanks!
