What is this? rerun (32 bit)

Over the last 6 or so months I have noticed a pattern where my laptop starts working very hard, all the cooling fans kick in and the hard drive activity goes way up.

When I check task manager, one of the main culprits is 'rerun (32 bit)'. Stopping the process doesn't seem to stop anything noticeable and the high activity levels slow down immediately.

I have not been able to find out what this process does, why it runs or whether it's benign or some kind of virus. I have had bitdefender for a few years now and never once has it identified this thing as a problem, but as it runs almost every day and my laptop can do without the flogging I'd love to know what it is - and if I can safely stop it!

Anyone have any knowledge of this? I run windows 10 pro, fully updated.

    After that, you will get an automated reply by the Bitdefender Customer Care Team, with your ticket number.

    Now, in reply to that automated reply, you can send the screenshot(s) you already took and the log files you already created in the first step.
