I think that file is infected. Here is result VirusTotal. Please check this file and add definition about him.
If so you need to send it to avast, as just posting a Virustotal report is no use…
also the scan report you post is 3 days old…
What i need to do?
Moving files to the Virus Chest
http://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=501#idt_03
Submitting files from the Virus Chest to avast! Virus Lab
http://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=501#idt_07
or send to virus @ avast.com in a password protected zip.file
mail subject: False Positive
Password: infected
It is recomended to use a zip program that also encrypt the file like win.rar or 7zip
