Security Central Malware

My computer got infected while I was browsing porn picture websites from a Google search. Yes, I know, I shouldn't have, but I did. Anyway, I tried everything suggested on your Read and Run Me First thread. I could download the programs, but Security Central would not let me install them. Therefore, I have no logs to attach. The message I kept getting was: "File is infected by W32Blaster.worm Please activate Security Central to protect your computer." I read the other threads related to this, but they seemed to be able to run their malware removal programs.

Any help you can provide would be greatly appreciated.
