I have a doubt many avs including norton and quickheal allow me to download the eicar test file and only after that they recognize and delete it. IF u see kaspersky and avast on the other hand instantly terminate the connection. Does that mean that norton and quickheal are not strong products please clarify. Also when i download zip archives of eicar norton and quickheal only remove the virus after its extraction or manul scan. Why so. Again kaspersky and avast block the download. Any ideas thnx.
