Hi everyone, I'm Lartigue in good old Kenner, La, just outside New Orleans.
Bought Norton 360, and ran a scan, no virus,
Bought Fix It Ulities, after installing it, window poped up saying C:\system volume information\_restore [90640718-8822-4594-9843-DDC9AD7DED22]\R815\A0002165.dll
But when I ran the Fix it scan, it said there was not a virus. But it also said it didn't go into the hidden or files being used by windows.
Downloaded Avast 4, ran a scan and it found the trojan and deleted it.
Always good to have more than one antivirus on your computer.

The infected RP***\A0000**** file(s) identified by your scan are in the System Volume Information Folder (SVI) which is a part of System Restore. This is the feature that allows you to set points in time to roll back your computer to a clean working state. The SIV folderis protected by permissions that only allow the system to have access and is hidden by default unless you have reconfigured Windows to show it.

Keep in mind that System Restore will back up the good as well as the bad files so when malware is present on the system it gets included in any restore points. When you scan your system with anti-virus or anti-malware tools, you may receive an alert or notification that a virus was found in the System Volume Information folder (System Restore points) but the anti-virus software was unable to remove it. Since the System Volume Information folder is a protected directory, most scanning tools cannot access it to disinfect or delete these files. If not removed, they sometimes can reinfect your system if you accidentally use an old restore point.

To fix this, you need to Create a New Restore Point to enable your computer to "roll-back" to a clean working state and use Disk Cleanup to remove all but the most recent restore point.
