I have had my laptop since like 2013 or 2014 and it was fine until like 2018 and 2019 when it started using 100% disk the whole time it was on. I scanned the laptop for viruses and found none. Most of the time its Norton Security and the system itself using up most of the disk (usually between 0.5 - 3 MB/s each) but not always. Not sure what is causing this and help would be appreciated since I kinda want to start using the laptop again.
