Prevx detects viruses which no other vendors can. When I uploaded these "viruses" to Virustotal,the result often could be 1/41. Today I uploaded a "virus" detected by the updated Prevx CSI to VT,the result is "0/41". And in the Prevx's website,they also provide detailed virus information like what this virus do etc. So has this virus already been analyzed by them? I often heard that Avira has many FPs but to me it never gives a FP in my pc since version 8. But I seldom hear complaints about Prevx's FPs which is really strange to me. Now I'm the one who wants to complain that "Prevx has too many FPs." By the way,the GUI is not user friendly either. I like Prevx. But I hope you make it better.
