Saw that your trial period for Norton Antivirus just ran out, so would like to suggest you try downloading and installing a free program from Microsoft called Microsoft Security Essentials (MSE), as you really don't want to risk your computer getting more infected.
I haven't used MSE myself, but others report that it does a fairly good job for a free program. Also, in addition to blocking and cleaning viruses, it is supposed to do the same for malware too, which is a big plus in my book.
Here is the website address you can download it from: http://www.microsoft.com/security_essentials/
Also, please give it another couple of days for one of the trained technical helpers to respond to your request for help. This forum gets a LOT of requests for help, so they are often temporarily tied up helping others. Please be assured, though, they will respond to you as soon as they can. Once the intial response gets made, it goes much faster after that.
