i have a file virus in .zip file (this virus file for test i have)
i use avast free scan it but it show not have problem (no virus)
but i use kaspersky free scan it delete normal

Why Avast free not find virus? ???

i Setting scan all Compression

Why Avast free not find virus?
Maybe it is new?

Upload file inside zip and test here www.virustotal.com
post link to scan result here

it find normal (this old virus )

Post link to virustotal scan result

Wait
https://www.virustotal.com/#/file/afd497e90d14e5f75984f717a69017cca4eb90af29f0229faa2161f10fff4d98/relations

So it is detected

if you right click on file and scan with avast it should detect

When uploading files to virustotal it is always best to upload file inside compressed archive (File Type RAR)
When uploading compressed file the additional info given will not be correct, it will be for the archive and not the file inside

Not find or i have extract file ? [[Virus].Rar].Rar
