I know next to ESET also Anvira, McAfee and F-Secure. In addition to the free version of Avira offers a good basic protection for PC's I find the ESET simply best. We have installed it on a per tablet and mobile phone from over half a year as a version that can be used for tablet and phone and was super easy, super fast and the protection is great as well. Thus a tablet has so much less RAM as a PC or a laptop - mine only 1GB RAM. But I realize none of this neither the scan nor the updates. However, I had only the beginning of some trusted app's also a false alarm. But I prefer to tell me one time too much and nothing warned than once too little and then have the damage. For the competition Installation took me recently with an account is created and permanent errors while an hour. User-friendly that was not. I am very happy with it because ESET was the only one in which everything went smoothly and quickly and got me so now on my laptop installed. I also get permanent no advertising mails as from the other. Please pay attention that only if one buys more licenses here with an activation code and then activate one time for all from the activation date. But when selecting one can choose suitable for his needs the number, year and performance.
Conclusion: I can not complain. The program is easy to activate and install and works very reliably and silently in the background. Good facilities for PC's you work with a lot on the Internet and surfs.
