Are you sure you've launched AVZ utility using "runas" option of the context menu? Even though you're working under administrator's account, you should use "runas" option to get correct results in your logs. Anyway I don't see anything harmful in your logs. There are some suspicius files there. If you want them of being checked, please, execute the script:
After restart, upload quarantine using the link http://virusinfo.info/upload_virus_eng.php?tid=54763 , as it's described in the app.3 of the rules.
QuarantineFile('C:\Program Files\Acer Arcade Deluxe\HomeMedia\Kernel\DMP\CLHNService.exe','');
As for this suspicious folder, I think it's normal - it's the way that Vista's protection works, but you can try to gain access to it using takeown command and look what is inside.
