There is no point in saying "No use. Can't upload it to VT." as we can't offer any suggestion. If we know why it can't be uploaded (errors given, how you were trying to upload it, etc.), then perhaps we can find a means to get round it.
This has nothing to do with A V G that you also have installed, but that has to be uninstalled in the normal way and possibly with another tool.
Uninstall possible remnants of previously installed AVs see,
http://singularlabs.com/uninstallers/security-software/, this has a collection of manufactures removal tools, so that should remove any remnants, registry, etc.

You have to understand the concept of suspicious activity - I see a many lurking in the shadows so I phone the police - it turns out that he was in the local neighbourhood watch monitoring the area - not suspicious any more. So avast does the same checks out suspicious activity and it may or may not find it legit on investigation.
