Trojan Virus

My Avast virus scanner says I have Win32: Trojan-gen {VB} in my C:\System Volume Information \restore {9DFDC7BF-3B3A-41AF-

I tell the pop up message to delete the infected file but It keeps coming back. How can I get rid of this permanently?

As has been told already many many times on this board:

1] Disable system restore
2] Reboot
3] Problem solved.

Start > Control Panel > System > System restore > Disable
Click Apply
Enable it again (if you wish)
Click Ok
