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.

    Hello toddh,

    normally pagefile.sys is not "deep-scanned", also note that the path refers to a ShadowCopy. Same day is likely coincidence.

    I'd say it's not a FP - but the path information could be incorrect (perhaps caused by the shadowing in progress). If you can spare the resources run a full scan (make sure it checks files with no extension - I'd expect these threats to be found in a browser cache).
