[Closed] Infection in son-in-law's PC - please help if possib

Merry Christmas. We are up visiting my daughter and son-in-law, and he asked me to help him eradicate some very annoying messages. I ran downloaded and ran AVG-Anti-spyware and found his PC infected with Trojan.ClassLoader.g and Hijacker.Small. I had them quarantined and rebooted into normal mode. He also has some desktop icons out there which I think are nuisanceware; Error cleaner, Privacy protector, and Spyware&Malware protection. Windows keep coming up alerting him to infections and to download these products to clean it up.

I downloaded Hijack this and the following is the report:
