A full 4GB root volume can have a huge variety of different causes. clamav is not the problem here.

Post the output of these commands:

# df -h
# df -i
# mount --bind / /mnt
# du -csh /mnt/*

They got trapped by the automatic spam filter. Periodically the mods check the filter, and manually release the false positives.

Looking at the details you posted, it appears to be fine now. The apps folder is normally a mount point to the data volume, so if you remount the root to /mnt, the apps folder should be totally empty.

  Hi Again everybody
  
  I seem to have failed in my solution. Problem is still there. As a last resort i think it would be wise to backup everything and do a factory reset.
  
  System volume root's usage is 88%. This condition should not occur under normal conditions. Contact technical support.
  
  I will have a last rummage around the root file maybe i missed something
  
  any words of wisdom more than welcome
  
  Thanks Patrick

    # du -csh /mnt/* 1.1G /mnt/var 1.5G total
    This suggests the problem is in /var. So you could do e.g.
    # du -csh /mnt/var/*
    and so forth until you find some big files e.g. some big log files.
    
    If in doubt, ask whether something is something you should empty or remove.
    
    If the anti-virus service is still running you should stop and disable that service. Maybe I was wrong and there could be some huge anti-virus related files still there.
