I have moved a CD/DVD-Rom from another system to the affected system. It allowed me to boot to a Windows 7 CD and I was able to reformat and re-install Windows 7.

After the re-install I was able to read media in the affected BDDVDRW drive and I was able to read USB sticks. I will know go about rebuilding the system with my programs.

I am very disappointed that although Avast IS recognized the scripts as potential threats, it did not block them and my system became infected with something unknown.

My concerns now are what code has been written to 2 hard drives other than the system drive and what code may have been written to other systems on my network (laptop, Win Server, wife’s mac). So far numerous scans of the 2 hard drives has revealed no threats. Is there any way to be sure?

Also, the 3 usb sticks that I tried on the affected system may have become corrupt. When I tried one on my laptop Avast indicated the U3 and PortableApps.com programs would run in the sandbox. I immediately removed the usb stick and have set all 3 aside. Is there a process to sanitize these?
