Windows Vista How do I remove start up "commands"?

I am running Vista Home Premium operating system. I recently ran a virus removal program and it identified/removed 5 virus/trojans. Now, everytime I boot up, I get messages that "The specified module could not be found" for two commands: (a) C:\user\name\EXLOAD~1.DDL, and (b) C:\User\name\AppData\Roaming\MICROS~1\Windows\STARTM~1\Programs\StartUp\SCANBD~1.DDL. Once I click "OK" the messages disappear and the computer appears to run normally.

Am I correct in assuming that these commands are related to the trojans that were removed and can be removed by editing the start up programming? If so, how can I do this?

Comments will be appreciated.

Thanks
