you still have spyware/addware installed on your commputer or a virus. you need to scan for a virus and for adware some more. it's definitely something you have running and you need to go through that list again. Task Manager will show almost everything. you probably need to go through the Startup list using some tool like Startup Cop to see every application that is being started. i presume you are running a firewall and antivirus software to prevent your computer from being hijacked.
