Yesterday Bitdefender was updated to 2018 version and since then there's been a 100% CPU usage spikes by process "System" every ~5 minutes. Using Process Explorer, it's been narrowed down to some avc3.sys processes which are Bitdefender drivers. I tried to reinstall it several times using Bitdefender Uninstall Tool but the problem continues to exist. Right now i am on Avast Free Antivirus and everything seems to be ok. I've been using Bitdefender for two years already and never expirienced such a problem. So what should i do? I really like Bitdefender and want to continue using it.
My OS is Windows 10 creators update with the latest build from August 9.
