Auto Protect disables notice wrong

I keep getting messages popping up that tell me my Symantec Auto-Protect is disabled.

I get other warnings about the firewall being turned off, etc.

Each time I check the configuration is OK.

I have Symantec Anti-Virus Full Version10.1.5.5000.

The only symptom is that the computer runs very slow at the beginning.

I've tried running Malwarebytes Anti-Malware (in safe mode) & ,of course, Norton full scan.
