Mods Update VirusTotal virus checks for existing files periodically.

I saw a mod which was labeled "safe to use" and downloaded it, but my antivirus went off. I checked the linked virustotal report behind the label, and it said that some security vendors had labeled it as unsafe.

I won't say which mod, in case it was a false positive, but does Nexusmods update virustotal check information for existing mods after they have been verified the first time? If not, please do so. Virus definitions are updated all the time, best to check existing files too.

You can trigger a rescan on files if required. You can report files that you feel need this button pressing

After pressing that button, the checkmark is still green, even though the file in question has been flagged like by 14 different security vendors. Does that mean I have to report it? What if it is a false positive, will I get banned for making a wrongful report?

If you're genuinely concerned, please use the report option. 

I will say though, all VirusTotal vendors are not created equal. If you've never heard of the ones that mark it as malicious, it's potentially just a poor quality detector
