Jhwellington, certainly it would be worth seeing if updating your firmware helps to resolve the issue on your device as well. As Kit mentioned though, all devices are different and can pose their own unique challenges. Firmware updates are device-specific.
The device isn't rooted is it? Changes to root permissions can have adverse effects on any installed software.
There are a few other things I would like to find out about this mobile device. Please follow the instructions below:
1) Open the Webroot Mobile App
2) At the home screen, press your Android menu button
3) Press "About"
What is the name of the software installed, " Complete, Premier, Free etc.." and what is the version number?
Also, is there any other security software installed or automated task killer app installed on this device?
If you unmount the sd card, does the scan complete?
If so, we might need to get logs from the device to see what's happening on this particular make/model. In order to collect logs, we would need you to open a support ticket with us. You can open one from this link: https://detail.webrootanywhere.com/servicewelcome.asp
The issue of the scan hanging on Archos devices was reported to be fixed by development shortly after this issue was reported.
