The Avast antivirus product on your home pc comes with various shields and therefore various layers of protection. Avast on virustotal is providing only basic file scanning.

when using VirusTotal always note the scan date at top of scan result

2019-01-23 17:00:30 UTC ( 1 month, 2 weeks ago )
So in your case a cached result (somone have uploaded and scanned that file before you)

A fresh scan give this result

also if you use the new VT website then there is a BLUE button at top right (after scanning) clicking that give you a "rescan" option if scan result is old
You can see this blue button in my scan result posted above

New website  https://www.virustotal.com/
Old website   https://www.virustotal.com/en/

Hi, Pondus, i have checked , and avast does not give any red rating. The scan result was furnished by the developers of the program . i have written to them first, why their program is found to be having some problem with avast antivirus and malware bytes.
He has replied that 2/68 was the rating of virus total . I found avast , giving the program green signal. This prompted me to write to this forum.
is it a false positive then for this program for me. please

If you think avast is giving you a false positive, then report it to avast lab
Only avast lab can answer why they detect / not detect

Report a false positive (select file or website)
