As more issues of this sort are showing up lately, I think this may be caused by
malware / trojan etc. It's a good idea to do a clean-up. Follow the advice given in
the following pages:
Generic Trojan / Adware Infestation Removal Procedure:

Once you're sure that the system is clean, disable the System Restore restrictions.
Follow this:
Click Start/Run and type REGEDIT
Navigate to the following key:
HKLM\Software\Policies\Microsoft\Windows NT\SystemRestore
In the right-pane,
Delete the value "DisableConfig"
Delete the value "DisableSR"
For Windows XP Professional, you can accomplish the above task using Group
Policy Editor as well. Details follows:
Click Start/Run and type GPEDIT.MSC
Navigate to this path:
=>Computer Configuration
==>Administrative Templates
===>System
====>System Restore
In the right-pane, do the following:
Double-click "Turn off System Restore" to "Not Configured"
Double-click "Turn off Configuration" to "Not Configured"
