The following procudure you must consider and perform at your own risk, as it appears to be the most logical thing to do, IMO.
Open Spybot S&D 1.3 and click Restore under the Spybot S&D heading.
When the Recovery list is populated, right click the first item and select 'Select all items older than 30 days' and then select 'Purge selected items'.
I would advise you to make a System Restore point prior to doing the above, although I do not personally use System Restore. As such, naturally, I cannot guarantee that System Restore will be successful.
Another thing to consider would be to backup important data, information, school/university/work projects, etcetera. This you should do as a matter or course anyway. Now is as good a time as any.
Taking into consideration my initial paragraph, good luck.........
