False positive or Not

So I ran avast full scan and found 4 viruses which are all named INI:shortcut Inf, 2 on the file poketalk with lenovo and 2 on lenovo telephony which strangely is an app that is already installed when I reformatted my laptop but before that I ran a full scan on mcafee LiveSafe which didnt seem to find any virus at all. Can you guys confirm whether the detection was false positive or not?? (sorry for bad english)

Test the file at VT (https://www.virustotal.com) and post the link to the result here.

dumb question but can you tell me how to upload it from the virus chest?
