Some free antivirus do come with a firewall, while others provide web protection for browsers.
The term “on-demand scan” refers to the possibility of performing a manual scan (by the user) on the entire computer/device, while “on-access scan” refers to the ability of a product to automatically scan every file at its creation and/or subsequent modification.

How Computer Viruses Spread
The best antivirus is ‘common knowledge’, having said that, this means not clicking on suspicious links when you receive emails with headlines that say you won something. This also includes downloading software from pirated sites.
Back in the good old days, people kidnap victims and demand ransom, some people rob banks. In today’s modern world, hackers kidnap your computer via ransomware, by locking up your computer with the data, until you pay the amount they demand, they will not release the key to unlock your files. Virus and Trojans no longer destroy your computer, they simply hijack it, sitting quietly and harvest your data, credit card and bank login password.
