what does it mean: a threat in "System Volume Information"?

[cfman]

I have met with this annoyance many times and I decide to take some time to
investigate this problem:

When I luanch my Symantec Antivirus 10.1 coporate client to do a full scan
of all my computer, it did not raise any alarm or detected anything.

But after a few hours, the "Auto Protect"(which was enabled and supposed to
protect me real-time) , due to unknown reason, raised an alert that there is
a file in "System Volumn Information" folder that was infected and got
deleted. But that file had always been there.

It was always like this: when you do a full scan, it did not detect
anything; but the real-time protect seemed to have more power and it can
detect something from time to time.

What's the problem?

The "problem" is that NAV can not delete the file located in System
Volume Information (System Restore).
Suggest you use Disk Cleanup to remove all but the most recent restore
points.
Start> All Programs(Programs)>Accessories> System Tools> Disk Cleanup
Click the More Options tab after Disk Cleanup calculates the space that
can be saved.
Click the Cleanup button under System Restore.

If that doesn't flush out the infected restore points, do not worry.
As long as infected restore points are not utilized, then the system is
NOT at risk of an infection.
For peace of mind, you can disable SR, and then reenable it to
completely flush the restore hierarchy.
Right click My Computer on the Desktop or Start Menu and choose Properties.
Then click the System Restore tab to be able to disable|reenable SR.
