i have a chromebook want to installation AVG antivurus.
Kit, Query… Do you need virus protection on a Chromebook?.. No antivirus software is needed. Chromebooks come with built-in malware and virus protection, with multiple layers of security: Automatic update system: Virus protection stays up-to-date automatically, so you are always running the latest and most secure version. Chrome manages your updates silently in the background.
Chromebooks don't get "viruses" because you can't install an executable program on a Chromebook.
