I am testing out ClamAv right now and I must say it's a fantastic product
from what I can tell so far. The next version will include the necessary
.dll files to perform local scans without an internet connection and support
for a few more file types.

I really do think this could be a replacement for a commercial Anti-virus
package, the source code is still GPL according to Sourcefire so that's
always a benefit.

That would be an option. I use clamwin to do scheduled scans, I never
thought of adding it to the task scheduler in windows. Since Microsoft
Security Essentials can only be used for home or home office use according
to their end user license agreement, I only use it in those environments. It
seems to work quite well. I installed it on my wife's computer at home and
on a couple of other peoples home machines. 
 The trend web protection seems similar to the new clam av for windows. They
both work in a similar pro active fashion in that they utilize the cloud to
detect malicious things freeing up local resources. Pretty neat !
