You can purge the restore points and that will cease those alerts, but prior to that quarantine the file and let Avast run a check on it every so often. But looking at VT this appears a good detection
Follow these steps to purge Restore Points:
1.Go to Start | All Programs | Accessories | System Tools | Disk Cleanup.
2.Select the More Options tab in the Disk Cleanup dialog box.
3.Click the Clean Up button in the System Restore panel.
4.Press the Yes button when prompted to confirm the delete operation.
The Disk Cleanup utility will allow you to delete allRestore Points except for the most recent Restore Point.

Sort of 50-50 on that. However, Dr Web does also detect it so it may well be a good detection
What problems do you have at the moment ?
Gays j have e problem avast detected trojan. c:/hiberfil.sys (j dont know where is it- j try to find end j dont have like this) avast call it Win32:L.mir-KO[trj] . j cant remove this and cant find it
I deleted all restore points. File is showing up as detected, even with the most current definitions. In your opinion, should I just leave it in Quarantine and for how long?
Leave it in the chest and once a week rescan it with Avast… If it still shows infected and you are experiencing no problems due to the lack of this file then you may delete it
