I'm having issues with my TrendMicro anti-virus software where my disk activity hits 100% for 10-15 minute periods randomly throughout the day. TM tech support has made a few suggestions but in order to track their effectiveness I have to monitor my disk activity in such a way that I can keep a log. Task Manager and PerfMon will show the activity but not keep a log. While there are free apps available I am reluctant to run any of them without a recommendation from a trusted source. Any takers? Or perhaps some vb.net code out there that might do the trick?
To further explain, I don't need to track what files are being accessed. I just need to track the percentage of disk activity like I see on the Performance tab of Task Manager (Windows 10) when I select a physical disk.
