Installed it after encountering some bugs (I'm surprised to encounter such!) like:
turning my screen to blink, like in the beat of the power LED when my netbook is in Sleeping Mode (it seemed like Bitdefender wanted a disco!) I don't know if that is caused by my system or an installation bug from BitDefender. But never encountered such like this before in any AV installation including BitDefender.
My first scans and cleaning of malwares were ssllloowww... I'll wait for Photon technology to adjust.. 360 and Emsisoft, which both uses BitDefender engines, were much faster to do scan and cleaning.
Some GUI bugs too...
Detections rates are HIGH and very good but NOT impressive. Unpacked a malware pack around two weeks old, but didn't detect 18 of them (190+ in total) in realtime and on-demand combined.
