BleepingComputer.com: When I type there's an extreme delay

Hey everyone, I'm new to this site but i have used it before to solve simple problems. My computer recently just suffered at the hands of "windows police pro" "anti-virus 2010" and some other vaugely named fake scan virus. I couldn't tell you how I got them, but all I know is i'm not letting anyone touch my computer anymore. After being at war with this virus' for about an hour, I finally got IE to open and i downloaded combofix, then afterwards i used malware bytes. Symantec and malware say that my computer is clean, yet ever since this ordeal typing has become a huge problem. There is an extreme delay between the key i hit and the character that shows up on screen. So much so that it will slow down all my other programs so the sentence i just typed can show up, Can anyone help me?


-Thanks
