No need to immediately download anything to "solve" the problem.

To help identify the actual source/cause:
What "charger" are you plugging in"?
Are the any utilities, tools, or even apps that are associated with the charger: i.e., tracking voltages, times, use, etc.? Did you download them and possibly picked up the malware by doing so? Likely some trickery or misdirection involved....
In Task Manager, be sure to check the Startup Tab. Could be something being launched early on Look for anything that is unexpected or unrecognized. Then investigate further as warranted.
Take a look in Reliabillity History. Reliability History may be capturing some related error code, warning or informational event that occurs just after the charger is plugged in and/or the Extension reappears. Event Viewer can be used in the same manner - not as user friendly as is Reliability History.
Also look in Task Scheduler. Not sure how it might work but there could be some app or other action being launched when triggered by the charger being detected.
