Taskeng.exe flagged as threat

Over the past few months, I’ve periodically gotten a notice that TaskEng.exe is infected with “Win32-Malware-Gen”. However, It’s located in C:\Windows\system32 and date modified is back in 2010… so I feel like it’s the actual Windows file. I get the notice from Avast maybe once a week or so. Is this a false positive? I keep thinking that there will be a program update and this will stop happening, but after many months, it’s still happening.

I’ve checked task manager and there is no taskeng.exe running, also no suspicious or hidden tasks in task scheduler. I DON’T ever see a black CMD window pop up like some google searches mention, only the Avast notice pops up.
