Nod32 or "microsoft safety center" problem?

[hghghh]

Hi,
I use NOD32 and when it scan my PC automatically, it see one infected file on the Restore Point. Then I open manually NOD32 I click on "In-depth analysis" and the antivirus doesn't see anyomere that virus.
And still I have configured NOD32 very well.
Why do I have that problem?
that virus is:
C:\System Volume Information\_restore{C09EEC88-D930-4E0B-A56B-DE10C11ED3B3}\RP30\A0011846.dll - Win32/Adware.WinAd Application
What can I do, please?
thanks

Hi hghghh,
the C:\System Volume Information\_restore path contains backups of previously removed or changed files.
To remove it please temporarily disable 'System Restore' and restart your computer to have this deleted.
Hope this helps.
