No doubt avp 3.5 ranks as one of the most effective av out there. Due to it's extensive unpacking engine it's detection of trojans makes it one of the best hybrid of av/at bar none. With it installed you don't need a supplementary AT. But if you want an updated av today, what's a possible substitute for it? Keeping in mind that this substitute should offer a reasonably strong unpacking engine, above average scan speed, light impact of system's resources, daily updates and solid track record against both virii and trojans. I think an av that comes close to this is RAV antivirus. Granted it doesn't have as strong an unpacking capability such as KAV (or any av with derivative engines) or Mcafee, it's up there with them. RAV have the feel of the classic avp in terms of its light impact on systems resources, small footprint and fairly quick scan speed plus it offers daily updates. What's anyones take?
