Win32:Hupigon-ONX [Trj] Virus!!

I was doing a boot time scan with avast, and it detected Win32:Hupigon-ONX [Trj] on a file called C:\hiberfil.sys .
And i cannot get rid of it because if I tryed to delete it, it would say: Could not delete because the share flags are incompatiable.

And i could not move to chest, or repair the file.

It could be a false positive in the hiberfile.sys could you reset the hibernate and then see if Avast still finds it

If it still finds it then you might want to exclude the hiberfil.sys file in the avastUI, Settings, Exclusions and copy and paste the C:\hiberfil.sys path into the new entry.
