and scan here
http://secunia.com/vulnerability_scanning/online/ for out of date & vulnerable common applications on your computer and update whatever it suggests. Download & use the PSI version ( not the OSI, in your browser java version) as I no longer recommend having Java installed on the computer at all, unless it is absolutely necessary, because of the too high risk of malware infiltration
Then pay an urgent visit to windows update & make sure you are fully updated, that will help to plug the security holes that let these pests on in the first place.
If windows update doesn't work, please come back & tell us
