On boot W7 desktop display Default BIOS settings have loaded

Specs: Windows 7
I used the computer last night, and the system shut down completely. I use a power center to cut power to the system when the system is not in use. Normally when I turn power on the power button on the tower has to be pressed to power the system up. This time the system powered up without me pressing the power button. The cdrom just kept spinning and there was no display. After about half a miinute I hard shutdown the system and restarted using the power putton on the tower. I got a screen showing that the default bios was used due to a Bios Update or checksum error. The system booted up and when I opened the administrators account, I found a warining notice from Mcafee Security Suitestating that realtime protection was turned off. I did not update the bios, and have turned on the realtime protection, updated the system and am processing a full virus scan of the system. I have updated bios on other systems and know the proceedure, my question is can a automated updates from Microsoft update the bios without my premission? And are you aware of any Viruses that can disable my security and change bios settings? Thanks

MS don't offer BIOS updates.

Viruses that attack BIOS are rare but anything is possible.

Viruses often disable security.

Doing your scans is a good first step. Also run MalwareBytes freebie on it as it often finds what AV's miss:

Most likely some sort of corruption.

Always pop back and let us know the outcome - thanks

Not a good idea. Even when the computer is idle, it is good practice to power of correctly, either power down via the power button or the task bar. Shutting down by powering of at the mains will sooner or later lead to a corrupted hard disk.

If I understand your post, you use a power strip to cut power to your computer AFTER you shut down properly? Is that correct?

Post the model of your computer.
