If you ask me, personally I recommend you to use Kaspersky Cloud Free + Malwarebytes. Low memory usage and more reliable. So far I using them for many years and it work perfectly fine and safe. I have experience with Norton/Symantec, Eset, Mcafee, Kaspersky, Bitdefender, Total AV, Avast, AVG and Vbuster (Malaysia brand) since 1993. I test antivirus to scan for all my collection of unknown and known viruses/malware. Kaspersky and Symantec won't my all time favourite. Norton or Symantec drain more memory than Kaspersky. Eset drain lower than Symantec but the software a bit buggy. Mcafeee and Avast I don't recommend coz the software not so reliable comparing to others. Vbuster use to be the best but I believe it was no longer in the market. Malwarebytes is more for anti-malware rather than as antivirus software.
