Take a look at this post. I also have CPU usage problems and simscan
installed.

I dont use simscan but use clamav for scanning emails passed from
exim. I noticed that cpu usage went through the roof and there was
dozens of clamd in sockstat. On a dual xeon it did cause some smtp
lag but on weaker specs it caused the smtp to completely backlog and
stopped emails arriving.
I downgraded back to 0.88.7 again and all is fine again.
