Pagefile.sys virus - False positive?

toddh

Hey,

I have a Sophos client reporting the following as multiple different viruses:

Virus/spyware Not cleanable Mal/Iframe-F \\.\GLOBALROOT\Device\HarddiskVolumeShadowCopy13\pagefile.sys
Virus/spyware Not cleanable Mal/Badsrc-C \\.\GLOBALROOT\Device\HarddiskVolumeShadowCopy13\pagefile.sys
Virus/spyware Not cleanable Troj/Fujif-Gen \\.\GLOBALROOT\Device\HarddiskVolumeShadowCopy13\pagefile.sys
Virus/spyware Not cleanable Troj/Iframe-CG \\.\GLOBALROOT\Device\HarddiskVolumeShadowCopy13\pagefile.sys
Virus/spyware Cleanup failed Troj/Badsrc-M \\.\GLOBALROOT\Device\HarddiskVolumeShadowCopy13\pagefile.sys


This showed up the same day as the now infamous Shh/Updater-B False positives

At first I ignored it because I figured it would start to show on multiple computers, but it didn't.

It only showed on a single computer so now I am not sure if this is a false positive or not. Can the pagefile.sys get infected by a virus?

Has anyone seen the behavirous before? And if so, should I take action to clean it? Or can it be ignored as a false positive?

Thank you.

    Please submit the file to labs for confirmation, at this point i would be cautious about deleting it from disk, currently it should be quarantined as it is in the logs. 

    Once you hear back from the SophosLabs you will be in a better position to decide. The Troj and Mal headers suggest they are malicious due to a different detection than the infamous 'Shh/Updater-B detection which is listed as:

    “Virus/spyware 'Shh/Updater-B' has been detected in "C:\Program Files\Sophos\AutoUpdate\ALsvc.exe".”
