A keylogger is a spyware program that records your key strokes, and then transmits them to a predetermined web address (an e-mail address, for example). Therefore keyloggers have the potential to steal your ID and password to almost anything, including your account on SRO.
Clean the keylogger, scan your entire hard drives, then change your e-mail address and password and other personal information as quickly as you can. Make that information useless before it reaches the wrong hands.
Do the same for accounts on other games/websites/e-mail addresses.
