I know that Vipre is new and there is not a whole lot of data yet on its performance against competing AVs, however ever since I read about the philosophy behind Vipre, I was intrigued and wanted to try it. I just bought it along with the SPF to run along and so far at this early stage I really like it. The system resource usage is indeed far lower than anything else I have run and the Mcafee it replaced was using approx 30% more memory just at idle with CPU usage at least twice as much. So with the install going flawless and the operatonal GUI looking clean and straightforward, I am so far pretty excited about it. The bad point on the SPF product is will only run on x32 with no x64 support but as I am currently running Vista x32 it is ok because I read that SPF does have x64 on its roadmap. So anyway I am looking forward to seeing how Vipre and the SPF do on my system over time. I feel pretty optimistic right now and expect to remain happy but you never know so only time will tell but the folks over at Sunbelt are top notch in my opinion and spent the time to correspond with me and work with me on my questions and purchases. This type of customer service is all too rare now and is yet another positive for the products development because I can see they care. I can tell you Symantec could sure use a lesson watching Sunbelt's customer service. So I was thinking of sharing my first impressions here and hoped any other Vipre SPF users will add to the thread and we can share in what little info exists yet for this new product.
