I hope this is in the right forum:
Specs (if more needed, please ask)
This next is the only major change I've made insofar as installations (nothing new besides it):
The time when I first detected this was 2 months ago when I removed my Avast 1 year trial and installed AVG free pro trial for a month (December), but disregarded it as I go through and add/remove a lot of files as a tech/gamer.
I then removed AVG when the Trial was up and installed Avast again under a new email address, and I noticed 2 weeks later that 629 out of a maximum of 685 gigabytes is full on my Hard Disk Drive.
When measured all of the folders in Computer -> C I came up with 400 something Gigabytes as per my previous note 2-3 months ago.
Subtracting this amount from the used 629 came up with a 163 gigabyte discrepancy.
Any thoughts, suggestions?
