Trojan System Volume Information Folder

I keep getting an error from my antivirus software stating I have a Dropper.Small.DE trojan on my computer.

The file location is C:\System Volume Information\_restore{03BC465D-33B9-4146-8166-8996776443E9}\RP239\A0094671.exe

I run the antivirus software, but the software cannot open the file.

I try changing attributes to manually go in and clean it, but it will not open.

I am logged on as Administrator….I don’t know what to do next.

It is XP home edition.

Any ideas?
