Your welcome.

Spybot S&D and adaware are lightweight (IMHO) when compared to these anti-spyware applications.

SUPERantispyware On-Demand only in free version. Or AVG anti-spyware (formerly Ewido) Resident scanner during trial On-Demand after trial ends. Or Spyware Terminator Resident scanner.

I don’t know how this other detection was found in the System Volume Information folder as that is usually associated with a deletion or moved file from the system folders and if that were the case I would also have expected you to have had an avast alert on a file in the system folders first.

It may be worth clearing all the old restore points and creating a new clean one (assuming your system is currently clean other than this detection).

Create Clean Restore Point - Clear old Restore Points.

Now you are clear of infection create a clean System Restore point:

  1. Click Start, All Programs, Accessories, System tools, System Restore.
  2. In the pop-up that appears fill in the radio button to Create a Restore Point
  3. Click NEXT
  4. Enter a useful name that you will remember if you need to find this again (Clean Restore Point)
  5. Click CREATE

You now have a clean restore point, you should clear the old ones:

  1. Click Start, All Programs, Accessories, System tools, Disk Clean Up
  2. Click OK on the C: drive
  3. Click the More Options tab
  4. In the System Restore section click the Clean Up button
