So what exactly is it that you were trying to do here in the creation of this VirusTest.vbs.vbs file ?
Doubly file types (VirusTest.vbs.vbs) can be suspicious and some AVs might alert on that alone, but it is usually used obscure the true intent of a file.
This isn't a malware building support forum, so we really need to know what your intention was in building this file.

Also remove the suspect script from your post, the last thing we want is for avast to alert on its own forums. If posting a script example use an image and not code to avoid alerts.
