if ya want.. go on to yahoo and search for "Trojan Cleaners". I'm sure, you'll bring up something half worth the download =)

also.. check your registry, system.ini & windows.ini.

and goto start--> run--> "msconfig" then, from there goto: startup, and look for any unknown, or interesting names "jlakjsd.exe" =)

good luck, and hope this has helped ya.
