Microsoft Windows Security Center_disabled

Hi,

I am using Norton Antivirus, SpyBot Search and Destroy, Ad Aware, & CCleaner and I keep getting this spyware/virus back on my PC. Can anyone tell me how to get rid of this? When I run Search and Destroy it detects the exploit along with one called TagASaurus. I tells me that it got rid of it, but I ran the program again just to make sure and it reappeared each and every time. Nortons also tells me that it was "fixed" after I run a scan.

Any help on this matter is deeply appreciated.

Thanks,

LG
