This is my first system filter, and I did have trouble with a more
complex condition so settled on

====================================
# Exim filter

#if ($message_body CONTAINS "LOVE-LETTER-FOR-YOU.TXT.vbs" and
#    $message_body_size is above 5k) then
#   freeze
#endif


if ($h_subject: IS ILOVEYOU) then
           freeze  text "Suspected ILOVEYOU virus"
endif                                                
====================================


But we are a relatively small site so can deal with false positives.

If others produce better filters, please post.
