One of, if not the best antivirus of the moment. Works in the background and discretely without loading the system. Bonus: serves startup and allows to create a CD to test the machine before loading the OS + a free license for my tablet or smartphone running Android. I know that for now, there is not too much danger for tablets, but sooner or later, vicious little will eventually deliver apps corrupted or spyware via dubious mails and as many make their PCbanking ... toy, so prevention is better than cure. In short, produced strongly advise.
