Hello firebird, Adaware isn't an anti virus program, it is an anti malware program... but anyway. I suggest you make sure that Norton is fully up to date and then boot into safe mode and run a full system scan, when that has finished run a full scan with Adaware in safe mode too.
To boot into safe mode;
Restart your computer
Start tapping the F8 key when the computer restarts.
When the start menu opens, choose Safe mode without networking.
Press Enter. The computer then begins to start in Safe mode.
