Inpite LowWaterMark closed the previous thread because maybe he didnt want to face the truth about Nod my question remains unanswered. Nod32 cant delete some viruses if they are running as processes in memory and also it cant delete viruses that exist in System Restore Folder. May someone explain to us why? We want the virus cleaned without booting in safe mode. Why Avast can and Nod cant? Avast was able to delete the 2 viruses that nod32 detected and couldnt able to delete it as well as killing the running memoery process of the virus. I beleieve Aavst is better but thaen again Nod is faster and lighter. But what matter i beleive its the efficiency of the product to delete virus, not the speed or the light resources. ps. Also i was not the one who started the insults.
