Hi micky77,
You have beaten me to it, I would like to give the same advice.
System Volume Information is your system restore points folder.
To get rid of it, Flush your system restore points:
To do this, you have to disable system restore and enable it afterwards again.
(note: this will delete all your system restore points and malware (adware in this case) that were present in it).
How to disable system restore see previous posting=====
After you disabled System Restore.... Reboot.. and after rebooting, enable it again, so a new system restore point will be made. A clean one now!
