I've just looked at your other thread and noticed you mention the clock and date are incorrect.
I'm not qualified to help you with security logs, but the clock could be a hardware problem. When computers start to show the wrong time and date, it can be due to the CMOS battery on the motherboard that needs to be replaced.
If the time is incorrect, it could possibly affect the way your antivirus software works, as it relies on the time and date being correct for updates and other features. Carry on with your other thread with the security analysts, but you could also try a new battery (
