ESET is the best
The vendor with the ideal antivirus software out there is ESET. You get ideal security for your money despite the fact that it is costlier.
Updating the virus database is done every day, file system safety is in real time, and installing/managing/handling staffs tools via ERA is possible for system admins.
Paid licenses are quite expensive, apps for iOS devices are lacking, and at times valid web sites are blocked by web access security.
