It’s not like traditional antivirus software, it just includes a tool that you can use to manually scan files to see if it has a virus signature, which is all Eset and most virus scanners are doing on the backend. They’re also doing what’s called heuristics, which is where they’re using predictive modeling to try and identify if a program has what they call an attack signature. This does result in false positives, just so you’re aware.
All virus total is doing is running a bunch of virus engines like eset and clamav on the back end to see if it triggers anything.
If both your virus software and clamav comes back clean, then I’d trust it.
A lot of the time these apps will have heuristics that will reach back out and so you will see network connections occasionally.
Without knowing more about this application, I don’t have the right context to evaluate whether or not I would trust something like that, so it’s gonna be up to your comfort level. But, if clamav came back clean and so did your other virus software, I would assume it’s not malicious traffic.
