pagefile.sys trojan?

Antimalware alert on access scanning detected a threat:

\Device\Harddisk\VolumeShadowCopy1\pagefile.sys is malware of type Backdoor.PoisonIvy.GD

Full scan throws up:

Backdoor.PoisonIvy.GD in path C:\pagefile.sys.

Disinfect and Delete options don't work and Quarantine runs but seemingly no action. Full scan message shows in red font and shows the same pagefile.sys but Bitdefender reports in green font "You are protected".

Is this an error?
