I try it the last time
One question: When I download the NavCoin Core 4.0.6 my kaspersky always deletes it: "FOUND: UDS:DANGEROUSOBJECT.MULTI.GENERIC" is that false positive? Just curious....
I keep telling the devs to frequent the place everyone found out about NAV but they insist on going on stupid platforms like slack and now its somewhere else.
In answer to your question tho (and I'm NOT a dev) As long as you downloaded it from an official source (Navcoin.org etc.) and not a link on a weird forum, it should be fine.
Many others have reported it shows a problem on some virus software but it's absolutely fine.
Hope this helps
