Some security software means *.drv are Windows device drivers and checks 
the complete file before you have read/write access.

Disable one of the Avast daemons to see, that is the problem you have. 
There is something in the "expert mode" of Avast, there you can stop or 
halt a single of the sub processes. If that is the the problem exclude 
the coLinux image file from scanner.

Rename the files "base.drv" and "swap.drv" into something that not ends 
with "drv", for example ".img" and change the names in config file. Than 
exclude this extension ".img" from virus scanner runtime scan.

All coLinux related IO counts you can check with
"watch cat /proc/colinux/stats"
(only in the coLinux devel version 0.8.x)

Or on the windows side you can find the task with "taskman" or the tool 
TaskExplorer from http://www.sysinternals.com
