I have just become a big fan of Quick Heal anti-virus now. Firstly, I must say that I never knew that it was an Indian Company and frankly, I always used to think that an Indian company can never make such great products but Quick Heal has really changed that.
I downloaded the trial version first and tried it out and found out that it was good and did not make my computer as slow as the previous anti virus thats a big win for me as I am a compulsive gamer. It also detected a couple of viruses from my Pen Drive which were not detected by the earlier AV.
I am quite happy with the way it is functioning currently.
