Putting Grub back after boot is messed up (like you reinstalled windows).

This is for Grub users. To reinstall Grub to your MBR:

NOTES:

• For "hd0,0" substitute whatever drive and partition your linux is installed on.
• For the "setup" command this is the drive you BOOT from

# grub
grub> root (hd0,0)
grub> setup (hd0)
grub> quit

Clamav Fix

Some time ago clam decided they would stop using 'clamav' as the user and switch it to 'clam'. This is pretty annoying since all the config file and such use 'clamav'. Here's how to fix the file ownership after clam is updated:

1. Find the appropriate files with: find /var -user clam
2. Change them all to clamav (owner and group)
3. Restart clamd and freshclam
4. Run freshclam

It took me a while to find all of these but the find command helped a lot.
