Avast says have malware infection on PC

Hello, I'm running Vista Home Preminium and my native anti-virus software-Avast free version-claimed I had 5 virus's one of which it quarantined. Knowing very little about malware and its removal I wondered if anyone could help.
Thanks

1. You should update avz bases (File/Database Update).
2. Make new logs.

Thanks Aleksandra, attached are the new logs.

What file to Avast's mind contains this virus? Your logs seems to be clean. I'd like suggest you to remove Bonjour: [url]http://virusinfo.info/showthread.php?t=42263[/url]

Thanks for the post Rene-gad,that would be great news if I'm virus free. Avast has put one file in its virus chest and after I used it's file repair option it now states I have no infected files as does Kaspersky's online scanner. But I'm distrustful and as I buy and communicate alot via the net I can't afford my security to be compromised-should I do another malware scan via Bitdefender?
