C:\hiberfil .Sys is infected by win32 : trone

while running bootscan Avasts 4.8…pro report this:C:\hiberfil.Sys is infected by win32 : trone
Repair:Error 42060 {The file was not repaired}
My SO is Windows xp pro. What should I do?
???

Have a look at the link,especially the last part about deletion.

Then try another scan

Seems a false detection of unencrypted signatures in the memory dump file of the hibernation process.
You can delete that file and it will be created again clean in the next hibernation.
