Just a quick note to help anyone else who's trying to get SCAVR http://www.jackal-net.at/tiki-read_article.php?articleId=1 working with Squid 2.6. It appears the redirect_program (url_rewrite_program) is now passed an extra field, the urlgroup. Line 683 of SquidClamAV_Redirector.py needs to be changed to read: url, src_address, ident, method, urlgroup = split(squidline) to make things work.
