System Restore overview
System Restore is a component of Windows XP that you can use to restore your computer to a previous state, if a problem occurs, without losing your personal data files (such as Microsoft Word documents, browsing history, drawings, favorites, or e-mail). System Restore monitors changes to the system and some application files, and it automatically creates easily identified restore points. These restore points allow you to revert the system to a previous time. They are created daily and at the time of significant system events (such as when an application or driver is installed). You can also create and name your own restore points at any time.
Restoring your computer does not affect or change your personal data files.
For information about backing up personal data files, see Backing up files and folders.
For an overview of the other recovery technologies provided with Windows XP, see Recovering Your System.
For more information about System Restore, see Understanding System Restore.
Antivirus utilities can affect whether your system can be restored to a previous point. If a restore point contains an infected file because the utility is not set to clean the file within the restore point, or if an infected file has been removed from a restore point by an antivirus utility because it could not be cleaned
, System Restore will not recover the computer to this partial or infected state. If System Restore could not restore your computer to a previous state, and you suspect that one or more restore points contain infected files or have had infected files removed by the antivirus utility, you can remove all restore points from the System Restore archive by turning off System Restore and then turning it back on.
For more information about System Restore, see System Restore overview. For information about using the System Restore Wizard, see Using the System Restore Wizard.

You should have had about three weeks worth of restore points. The fact that you did not would mean that it would be a good idea to check for malware on your computer.
Here are a few on-line scans which I would recommend you run using Internet Exlorer (they require Active X)Web based online Antivirus and anti-malware scans:
