EA Javelin anticheat encountered an error

Anti-cheats works on a kernel level, meaning it's the highest level of control over someone's system. My theory is that Microsoft Security is somehow preventing Javelin kernel level access. If you guys haven't tried, try disabling Real Time Protection in Privacy settings and it might work.  Also, try Steam if EA app is boofin. FYI: you don't need anti-virus if you're smart/aware about what you download on the internet. Sites like VirusTotal are great at finding base level viruses for downloads.
