Another thing I might add,is that when you find the time to do what has been suggested and post the results here.After the pros have taken a look and come up with a game plan and after your system is deemed clean,that you should look at updating your XP to SP2,since this will add patches that may protect you further.Please wait to do this until you have gotten the all clean from the people here,since you don't want any problems following you and messing up the installation of the new files.
