What antivirus app do you use?

Add stellaris.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.  

WreckerSharp said: Paradox won't let me post what I want to say. Apparently it's spam-like or doesn't fit within their content guidelines. They don't want anyone to actually say that this game doesn't work.

Users with small numbers of posts cannot include links. This is an antispam measure. You can post anything else just fine.

If you describe your problem in more detail I'm happy to help. Thanks.
