Kaspersky has always had the highest detection rate for me. It is also one of the most lightweight antivirus softwares, (with the exception of free virus protection solutions like Avira or Bitdefender Free).
I do not skimp on antivirus however, so the endpoint security serves the right balance between the two, for me. Why you must choose a paid antivirus such as the End point security package, is because hardly any free softwares provide all of - web protection, malware protection, mail protection etc. Bottom line, this one will keep you safe both on the internet and off it.
The event log and quarantine are just how I'd have liked them to be. I allow Kaspersky to take all the decisions it needs to, and check in on the event log later to restore anything that may have been accidentally been identified as a threat (which is rather rare, unless you regularly use pirated software).
