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.

    Thought I should resurrect this thread having encountered an admittedly very few (less than 10 from about 4000 clients during several weeks) similar detections lately (both on 10.0 and 10.2). All in a shadow copy, not all in one of pagefile.sys though (a tmp.ebd belonging to MS Search is another example). Detections are Mal/EncPK-xx, Troj/Badsrc-xx.

    I'm not yet incined to take this to Support given the prevalence of this spurious detections.
