thanks, it seems to me that avast has quarantined it, so to upload it to virus total I should remove it from quarantine? 
What was the link to the VT results ?
I would leave it there for now where it can't do any harm.
The process that triggered the alert looks somewhat strange, is that known to you ?
Whilst it isn't unheard of for MicrosoftApps to communicate with the internet, this path to the HrTxr.exe looks strange at the very least. Do you use any Microsoft communication apps ?
EDIT: I didn't read your reply very well I thought you had uploaded it already, presumably yo only have the HrTxr.exe file in quarantine. If so don't restore it back to its original location or whatever triggered it could do it again.
Go to the Quarantine and hover the mouse pointer over the entry - that should display a trash icon and three dots, this gives other options, don't use restore and add exception (or next time it wouldn't be blocked). Create a temporary folder anything really, but a name which would make it obvious what it is, Temp-Quarantine, somewhere you can easily find it. Add that location to the Avast exceptions so it doesn't alert when you sent it there, use the Extract option. See attached image.
Now you should be able to upload it to Virus Total.
