No, summer that program you have and scanned with is the AVG Free Anti-virus program.
Good program for sure. But we also need you to download the AVG Anti-spy program, also version 7.5.
You will find that in the link that PP gave you. Follow his instructions there on the download, install and update. This should be run in safe mode and set to fix or quarantine anything found. It may very well remove your trojans but we won't know until you run it, have it clean and then save the log and post it back here.
