Different Between Antivirus' Database with Cloud Scan's Database?

Hello… I have a question… In a poor English… Sorry… :cry:
Antivirus and Cloud have their own blacklist’s database (known as malware). Both of them can detect a malware and give a alert…

  • What is the different between both of them?
  • Is the Cloud scan database bigger than antivirus database on CIS?
  • Which have the up to date database? Antivirus or Cloud?

Thanks a lot for the reply…

Cloud always has the latest definitions, its there to catch what the AV local database doesn’t cover until the next definition update.
