Why do it so complicated?
take picture of computer screen with phone (have you never heard of print screen or snip tool ?) then upload picture to imgur, and then post link to picture at imgur ..... when you can just copy paste the scan link from virustotal
Also all the additional file info that can be very usefull to find out if it is a false positive or not, is not visible to us .... it is if you post VT scan link
