Last time i got teamviewer support, the tech installed this beta or unreleased firmware on my router.

Works since then. but then suddenly my router started to stop broadcasting my wifi once in a while, so i do restarts. And have it on a weekly schedule to restart while im asleep.

I started to notice the antivirus turns itself off after restart. When i turn it on manually, it give me message that fail, then goes to try and update security database. Next restart, it's off again! I let the security system database update, come back to look an hour later, it still says "Your security database is updating..."
