Windows with Networking, Safe Mode

I used Windows safe mode for several days to stay up and do my work. Can someone discuss this feature in some detail? I am experienced, but not with safe mode. It stabilized my laptop during an attack by Antivirus2008.

You should really read Microsoft's documentation about safe mode.

In a very short description:

Safe Mode doesn't allow everything to run.
