Mcafee's uvscan is good enough and quite cheap (if you opt for the SMB 
edition multi-user pack). Plus the newer engine (5xxx) is quite low on 
resource usage compared to the previous versions and virus defs are 
released daily (sometimes multiple times a day)

BTW, for those using speedownload.nai.com (see the archives) are 
recommended to change to ftp.nai.com.. the download speed difference is 

Also i find bdc quite annoying on the CPU usage.. to consider it for 
long term usage.
