Bitdefender user since version 7 (and therefore a "forever" at least in computer) I have rarely been disappointed by this virus following the excellent value for money (unbeatable by all other suites if one takes into account the number of items from which it can be installed, unlimited number of devices, for 5 users and all this for 2 years). This suite is quite light and very good results in tests carried out by all the specialist press (always comes first or second in a handkerchief). It seems that this version (Total Security Multi-Device) is the perfect version for a family (multiple fixed and / or mobile PC, smartphone and tablet) but I have not tested parental control (not 100% but in the case of any software of this type). But not only for families. In my case, I installed it without any worries (really unlike any previous version there are 2 or 3 years) on 2 PCs running Windows XP (SP3 imperative does not install if only XP sp2), a laptop with Windows 7 3 4 Android smartphones (Samsung Galaxy S2, Samsung and Samsung Note1 Note2) and a Samsung 10 "tablet 2012 GT-P7500 Android model 4). I highly recommend to create a Bitdefender.com account to manage your devices particularly smartphones that can "manage" remotely if lost or stolen (lock the phone, delete the content, geolocation, send a text message or him to make a sound ... I tested and for me it works very well). Another advantage is less known Bitdefender as the license is 2 years, next year you can take the free upgrade to version 2016. The installation can be a bit long but it is due to the fact that before installing it does a scan of the PC and it does an update during installation (can be disabled option but I do not recommend) followed by a PC reboot. By default, it updates (virus database) every hour and sometimes it increases the CPU load, but not all the time and always without slowing down my PC. Several tools built into this suite (strong safe deposit box, optimization of the base of the Windows registry, ....). I have not tested either the SafePay function which seems to complain another user (Pascalou). I never had a problem of infection since using Bitdefender, it is also true that I never surfing questionable sites (hacking / download illegal content ...) by against a PC used to manage a coalition of about 230 organizations (over 4,000 members) with whom the exchange of emails everyday and it has for several years (with several members of pirated mailboxes have not "succeeded" to infect me). In short, I recommend it and even I always advise my entourage.
