Bitdefender, the Romanian antivirus created by SOFTWIN is unarguably the world’s best antivirus. Personally I have researched many AV’s rt from Norton to Nod32 but none is close to Bitdefender in case of performance. The latest edition Bitdefender 2009 has many new features like gamer mode and laptop mode that use feeble resources
The virus detection rate is almost 98.55% and detects almost every virus and malware. Also it is very light on system using very low resorces. The pricing is also very competitive. Daily updates are available through auto update feature, So no worry of new detections.
The Pricing is ok and cheaper than most of the other AV’s available.
Bitdefender has been rated best by many independent antivirus testing agencies like :
Westcoast labs , Vb32 , ICSA Labs , CHIP , Digit, Av comapratives and many more
Also it has extra features like AntiPhishing and Identity control which are very good.
