I have today downloaded Ad-Aware Free 8.2.0. However, it shuts itself down after only 34 seconds into the scan. I am operating Windows XP with Windows firewall and AVG anti-virus. (I am not using Norton.) I did try uninstalling it then re-installing it but the problem remains. Does anyone have any suggestions as to what might be going wrong or where I might find version 8.1.4 which seemed to work OK. Thank you.
