Because, again, there is no virus in the files.
Let me ask you somlething: did you use an anti virus before getting the one you've got from somewhere (that you're apparently paying for now) or have you always been using Virus total believing it was an anti virus when it's only here to scan your computer.
VirusTotal profits off the uploaded binaries by charging a subscription fee. VirusTotal provides no recourse available when legitimate software is marked as malware, only to contact each individual anti-virus company to report the false positive.
