That is the idea, check against multiple scanners and if avast is the only one detecting it then it is likely it is a false positive detection.

Now you need to send the file/sample to avast so they can analyse it and correct the signature detecting it. Click on the Mini Sticky link to see how to send it to virus @ avast.com. You will also need to add it to the exclusions as I mentioned so you can continue to use the program without avast detecting it and do the periodic checks as previous post.
