Also, it's a little more advanced but is it "scheduled"? (look in the Windows Scheduler.)
The calculator on my wife's desktop keeps launching, sometimes as many as 10-15 times.
I have run McAfee, Avast, Malwarebytes, Spybot and still it comes back.
There's Norton, Kaspersky and other antivirus systems.
The tools I noted such as AUTORUNS is not a repair tool. It only lets me see what it could be. I would have to check each area out.
--> I sometimes forget that folk may not search for prior answers too. EXAMPLE:
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
