I installed Kasperksy to a 64 bit windows 7 installation (part ofthe beta options recommended by W7 upon installation). It is working nice and nifty. No problem with performance, updating and scanning and all. However, when I tried out systems diagnostics, "no anti virus" detected was flagged. Suggestions offered, to include disable anti virus operation at the security center... checked it out there but firewall options were already off. Any theories?
