I was made a repair I have a customer who had a viral infection. Logic that in I arrived I saw that she used Avast. I thus uninstalled it and put a version trial of Nod32 to clean her PC. And there as soon as I began the cleaning the threats detected did not stop climbing. The analysis and the cleaning to last more than 10hours. I have never seen that since I am in the computing. And the PC of the lady worked it was not planted. Like that can arrive this kind of viral pandemic?
