The best anti virus I used for my laptop is quick heal anti virus, even I also used avast, avira, and some other antivirus but I feel quick heal total security is best .generally some anti virus scan your files but could not recover your file but this will recover your file, it will get secure you from the virus which comes from internet, it also blocks the site where it will found virus, and you can also scan your mobile from this anti virus.so this is the best anti virus from my point of view.
